Anna Soter Wants to use Exotic Atoms for a Subtle Experiment
Gravity accompanies us in our everyday lives—from early morning, when we get out of bed, to late evening, when we drop tiredly onto the mattress. Although no other force of nature shapes our lives as much as gravity, we still know little about it. Many scientists around the world are working to uncover the secrets of gravity. One of them is researching in Canton Aargau: the 32-year-old particle physicist Anna Soter.
Astroparticle Physics European Consortium (APPEC) elects the new Scientific Advisory Committee Chair and the new General Assembly Chair.

Further reducing the error
Laetitia Laub was born and raised near Lausanne. She studied mathematics and physics at the Federal Institute of Technology in Lausanne (EPFL). Since August 2017, the 24-year-old junior scientist is writing her doctoral thesis in theoretical physics at the University of Bern. In her thesis she deals with the anomalous magnetic dipole moment of the muon and the reaction of this particle in the magnetic field. "Many people are currently working on this theoretical problem with the aim of further reducing the calculation error of the dipol moment. This is also because a better experimental value for the dipole moment will be probably found at Fermilab in the US and J-Parc experiment in Japan soon, " says Laetitia Laub.
The risk of thorium-based nuclear power would be acceptable
At the end of August, climate change and the future energy supply of Switzerland were among the topics of several keynote speeches at the Annual Meeting of the Swiss Physical Society (SPS) and the Swiss Institute of Particle Physics (CHIPP) in Lausanne. Maurice Bourquin, former professor of physics at University of Geneva, gave a keynote lecture about the ongoing transformation of the Swiss energy system. Professor Bourquin was also Rector of the University of Geneva (1999 - 2003) and President of the CERN Council (2001 - 2003). The 77 year-old scientist’s speech was titled: “Thorium-based systems – A new direction for nuclear waste elimination and energy production.” In the interview that follows, Professor Bourquin explains why he still believes in nuclear power.
Claudia Tambasco honoured with CHIPP Prize 2018
In order for physicists at CERN to carry out their experiments for the understanding of matter, the large particle accelerator LHC must be operated with the utmost precision. Ensuring this precision both now and in the future was the overriding goal of a doctoral thesis that Claudia Tambasco recently completed at the EPFL in Lausanne. For this work, the young researcher was today (28.08.2018) awarded the prize of the Swiss Institute of Particle Physics (CHIPP) at a ceremony in Lausanne.
Long-sought decay of Higgs boson observed
Geneva, 28 August. Six years after its discovery, the Higgs boson has at last been observed decaying to fundamental particles known as bottom quarks. The finding, presented today at CERN by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC), is consistent with the hypothesis that the all-pervading quantum field behind the Higgs boson also gives mass to the bottom quark. Both teams have submitted their results for publication today.

Results from XENON1T, the world’s largest and most sensitive detector dedicated to a direct search for Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs), are reported today (Monday, 28th May) by the spokesperson, Prof. Elena Aprile of Columbia University, in a seminar at the hosting laboratory, the INFN Laboratori Nazionali del Gran Sasso (LNGS), in Italy.
Swiss team will participate in the second European Physics Olympiad 2018
Five of Switzerland’s best-in-physics high school students will take part in the European Physics Olympiad, which will be held at the Moscow Institute of Physics and Technology in Russia from May 28 to June 1 this year.
Measuring the Invisible Cosmos
In 2021, the European research satellite Euclid will be launched into space. With Euclid, scientists from Switzerland and 15 other countries want to gain a better understanding of dark matter and dark energy. These two 'things' fill large parts of the universe in the view of modern astronomy, but neither dark matter nor dark energy have been directly observed so far. Researchers at the University of Zurich have prepared a complex computer simulation of dark matter in preparation for the Euclid mission. This mission is of great interest not only to astronomers and astrophysicists but also to particle physicists since particle physics is on the quest for the discovery of the nature and structure of dark matter with its own experiments.
The best way to new physics
If you are looking for unknown things, you usually do not know which way to go to find the unknown. This dilemma is also faced by scientists who want to advance into previously unknown areas of elementary particle physics. And yet they have to find a consensus on which experiments promise the greatest gain in knowledge in the next years and decades. For this purpose, the Swiss particle physicists are currently working on a new research roadmap.
Mobile phone sensors, fit for cutting-edge research
The large particle accelerator LHC at CERN in Geneva enables scientists to get precious clues to understand the nature of matter in the next two decades of data taking. The power and performance of this huge research apparatus needs to be constantly improved for this task. A silicon sensor, which the junior researcher Claudia Merlassino is currently testing at the University of Bern, is planned to be used from 2025 in a large LHC experiment: ATLAS.
Drugs from the particle physics research lab
CERN in Geneva is the world's largest facility for the study of fundamental particles. The equipment that usually serves science can sometimes be used for practical purposes too. That's for example the case for the protons emerging from the Proton Synchrotron Booster (PSB): they are used in the large particle accelerator LHC for scientific experiments. The protons can also be used to produce isotopes that are useful in radiation medicine. Such isotopes are produced in the recently opened facility CERN-MEDICIS.
A Touch of Magnetism
This fall at the Paul Scherrer Institute, the construction of a new particle physics experiment will begin to determine the electric dipole of the neutron. It will replace a previous experiment, which has performed the so far most sensitive measurement in recent years and for which data evaluation is still ongoing. The new experiment, co-developed by ETH Ph.D. student Michał Rawlik, can detect almost inconceivably small features of magnetism. A successful outcome of the experiment would help explain why there is so much more matter in the universe than antimatter.
An Unimaginably Sharp Image of Antiprotons
Researchers of the Baryon-Antibaryon-Symmetry experiment (BASE) at CERN have achieved a remarkable success: They have determined the magnetic moment of the antiproton with a previously unattained accuracy. The measurement is more precise than the best measurement for the magnetic moment of the proton.
T2K presents hint of CP violation by neutrinos
The international T2K Collaboration strengthened its previous hint that the symmetry between matter and antimatter may be violated for neutrino oscillation.
LHC provides data again
After a half-year break, the Large Hadron Collider (LHC) at CERN will go into operation again in June. During the last few months, intensive maintenance work on the particle accelerator has been done. The physicist community is hoping to gain new insight into the building bricks that make up our world.
Artistic View on Physics
The highly complex research of elementary particle physics is for most people not immediately comprehensible. An artistic approach can help overcome the inaccessibility of this discipline and make particle physics understandable. This is the basic idea of the art @ CMS program, which is celebrating its five-year anniversary this year.
Voyage aux confins de la physique
Aussi compliqué que puisse être la physique des particules, les expériences du CERN permettent de se rendre compte du travail des chercheurs dans ce domaine. Les physiciens théoriciens, par contre, ont plus de peine à communiquer leur travail qui repose sur des modèles mathématiques. Un projet de l'EPF de Zurich tente maintenant de rendre facilement compréhensible un domaine de recherche de la physique théorique actuellement très en vogue: le principe holographique.
Heart surgery at CERN
During the recent service pause of the CERN Large Hadron Collider (LHC), a key component of the CMS experiment was replaced at the beginning of March: the new pixel detector is even more powerful than its predecessor – raising hopes for new insights in elementary particle physics.
Research as a peace project
The laws of particle physics apply regardless of place and time, but the laws can’t be explored or their applications studied equally well in any location. Particularly in poorer countries, cost-intensive research projects face big challenges. Against this background, there is a ray of hope that the first Synchrotron in the Middle East for the production of high-brilliance X-ray radiation, called SESAME, will be launched during summer 2017. Switzerland has contributed to the success of this project.
Blocked future
The Chinese writer Cixin Liu has landed an international bestseller with the novel 'The Three-Body Problem'. Now his story about the fight between the Earth and the Trisolaran population is also available in German translation. In the dress of a science fiction novel, the 53-year-old author expresses his deep conviction: without fundamental research in physics, technical progress remains on the line.
"Making physics vivid and interesting"
Bahar Behzadi, physics teacher at the Freies Gymnasium Zürich, participated with her pupils in the last year's competition "Physics in Advent".

Indeed, teachers from Swiss schools are invited to participate in the competition with their class. One of the prizes is a class trip to CERN.
"Like the CEO of a multinational company"
The abbreviation CMS stands for one of the currently largest physics experiments worldwide. Günther Dissertori, a particle physicist at the Swiss Federal Institute of Technology (ETH) Zurich, was recently appointed to the three-headed spokesperson-team of the CMS experiment, which is located at the large particle accelerator at CERN in Meyrin near Geneva. The 47-year-old scientist has to cope with a task that can be compared to the management of an international company with 4,000 employees.
Track and trap – the long search for magnetic monopoles
Is there an elementary particle carrying magnetic charge? This fundamental question is being addressed by an experiment currently performed at CERN near Geneva. Recently the MoEDAL research collaboration published its first findings. No discovery has been made so far, but now the experiment will enter in its hot period. Prof. Philippe Mermod and his team at the University of Geneva play a vital role in the search for the hypothesized fundamental magnetic particle.
Precision with a Broad Benefit
Marco Valente is a PhD student, born in Ticino and is currently working at the University of Geneva. He is evaluating the performance of a method from which it is expected to improve important measurements of the ATLAS experiment at CERN. For his current studies, the 23 years old researcher has just been awarded with a poster prize given by the Swiss Physical Society (SPS).
Mohamed Rameez wins the CHIPP Prize 2016
The prize of the Swiss Institute of Particle Physics (CHIPP) 2016 goes to Mohamed Rameez. The 27-year-old neutrino researcher who just has earned his PhD at the University of Geneva has been awarded for his outstanding contributions to the IceCube Collaboration.
Le deutéron a son énigme, lui aussi
Le deutéron – l’un des noyaux atomiques les plus simples, composé seulement d’un proton et d’un neutron – est nettement plus petit qu’on ne l’avait imaginé jusqu’ici. Ce nouveau résultat, obtenu par un groupe international de recherche qui a mené des expériences à l’Institut Paul Scherrer PSI, va dans le même sens qu’une étude datant de 2010: les chercheurs avaient alors mesuré le proton et obtenu une valeur nettement plus petite que d’autres scientifiques, qui avaient recouru avant eux à des méthodes d’expérimentation différentes. Le résultat de 2010 avait marqué le début de ce qu’on appelle depuis l’«énigme du rayon du proton». Le nouveau résultat de mesure de la taille du deutéron révèle à présent une énigme analogue. Il entraînera probablement l’adaptation d’une constante fondamentale en physique, la constante de Rydberg. Autre explication possible: une force physique inconnue à ce jour serait à l’œuvre. Pour leurs mesures, les chercheurs ont mesuré par spectroscopie laser ce qu’on appelle le deutérium muonique: un atome artificiel composé d’un deutéron autour duquel gravite une particule élémentaire exotique dénommée muon. Les expériences ont été menées au PSI, car c’est là que se trouve la plus puissante source de muons du monde, nécessaire à la fabrication de suffisamment de deutérium muonique. Les chercheurs ont publié leur nouvelle étude sur la taille du deutéron dans la prestigieuse revue spécialisé 'Science'.

Entrée dans la 'nouvelle physique'
Depuis début juin, le Large Hadron Collider (LHC), le grand accélérateur de particules du CERN, a été remis en service après une pause de deux ans pour révision et fournit de nouvelles données expérimentales. Les données devraient pouvoir permettre aux scientifiques d'acquérir de toutes nouvelles révélations concernant la structure de la matière. Un des physiciens impliqués est Tobias Golling (39). Le physicien des particules formé à Fribourg, Heidelberg, Bonn et au Fermilab de Chicago enseigne à l'Université de Genève depuis l'automne 2014 en tant que 'Associate Professor' et effectue des recherches dans le cadre de l'expérience ATLAS du LHC. Selon Golling, grâce aux données fournies par le LHC au cours des prochains mois, l'image mondiale de la physique moderne pourrait avancer d'un grand pas.
Prix CHIPP 2015
Dans la célèbre pièce de théâtre de Johann Wolfgang von Goethes, le savant universel Heinrich Faust demande ce qui assure la cohésion interne du monde. En vue de trouver une réponse, Faust se voue même à la magie. Dans son doctorat, la physicienne de Bâle Lilian Witthauer se penche également sur cette grande question. Elle n'a pas trouvé de réponse dans la magie mais grâce à des expériences sophistiquées sur des accélérateurs d'électrons. La grande qualité de son travail scientifique lui a valu l'honneur de recevoir le prix CHIPP 2015 le 29 juin.
Anniversaire SCNAT
Cette année, l'Académie suisse des sciences naturelles (SCNAT) fête son 200e anniversaire.

Hawking en film: 'Une merveilleuse histoire du temps'
Lorsque la physique arrive dans les salles de cinéma, il s'agit en général de science fiction. Le film anglais 'Une merveilleuse histoire du temps' donne un tout autre aperçu. La production cinématographique de James Marsh (régie) et Anthony McCarten (scénario) place l'astrophysicien Stephen Hawking et sa relation avec sa première épouse Jane au centre d'un récit biographique. Le film décrit la dégradation physique du physicien qui souffre de dystrophie neuromusculaire, ALS (maladie de Charcot), et il raconte comment l'épouse d'Hawkings fait don d'elle-même et s'occupe de son partenaire autant que ses forces le permettent et lui reste fidèle.
Débat Genève
Le débat du mercredi 10 décembre entre Ruth Durrer, professeure de Physique à l’Université de Genève, et Christian Gonzenbach, artiste genevois promettait d’être riche et passionnant. Promesse tenue.
Les positrons gardent encore leur secret
Grâce à l'expérience AMS pour la mesure du rayonnement cosmique, les astrophysiciens espèrent en découvrir plus sur la mystérieuse matière noire dont notre univers doit être gorgé mais dont la nature demeure inexpliquée. Les derniers résultats de l'expérience AMS ne fournissent pas encore de découverte décisive, mais ils apportent, avec la participation de l'université de Genève, un aperçu dans le rayonnement cosmique d'une précision inconnue jusqu'à présent.
Débat Particle Fever
Au Swiss Science Center Technorama de Winterthur, le physicien du CERN Hans Peter Beck, le scientifique en communication Mike Schäfer et la socio-psychologue Clara Kulich ont discuté des possibilités et des limites de la communication dans le domaine de la physique des particules auprès du grand public. Le documentaire 'Particle Fever' du régisseur américain Mark Levinson sur la découverte du Boson de Higgs a fait l'objet du débat. La première alémanique du film a eu lieu le 1e octobre 2014 dans l'Auditorium du Technorama.
Visite chez les descendants d'Einstein: Film 'Particle Fever'
Comment recherchent les physiciens modernes ? Mark Levinson répond à cette question dans son documentaire 'Particle Fever'. Le film célèbrera son lancement alémanique ce mercredi au Swiss Science Center Technorama de Winterthur. Nous avons visionné le film au préalable. Une discussion.
Débat Neuchâtel
Le CERN à Meyrin près de Genève ou le projet Human Brain sur l'Arc lémanique sont deux paquebots qui concentrent de nombreux scientifiques et des moyens financiers importants. Au détriment de quoi ? La question a été débattue lors d'un débat à Microcity à Neuchâtel.
Interview Big Science
Le Microcity de Neuchâtel a été inauguré en mai 2014. Avec ce centre de microtechnique, le canton de Neuchâtel et l'ETH de Lausanne souhaitent renforcer le site de recherche de Neuchâtel. Mais comment Neuchâtel s'impose-t-il face aux grands projets de recherche comme le laboratoire européen de physique des particules de Genève (CERN) ou le projet phare européen Human-Brain-Project implanté à Lausanne ? A ce sujet, une discussion avec le journaliste scientifique Dr. Eduard Kaeser de Berne.
Débat CERN
Pendant le congrès annuel commun des organisations physiques CHIPP et SPS le 2 juillet à l'université de Fribourg, d'éminents intervenants ont discuté de « l'influence du CERN sur la Suisse et sa société ». Le débat organisé à l'occasion du 60ème anniversaire du laboratoire européen pour la physique des particules (CERN) a abordé la grande utilité ainsi que les occasions manquée.
CHIPP Prize 2014
ETH doctoral candidate Marco Peruzzi has been awarded the CHIPP prize 2014 at the CHIPP annual meeting in Fribourg. The 26-year old physicist of Italian descent analyses the so called diphoton decay in the CMS experiment at CERN. His research is a valuable contribution to a better understanding of the Higgs-particle.
60 ans CERN
Olivier Schneider, prof. de physique des particules élémentaires à l'Ecole polytechnique fédérale de Lausanne (EPFL), est le président du 'Swiss Institute of Particle Physics', l'organisation qui comprend tous les physiciens des particules travaillant en Suisse. A l'occasion du 60ème anniversaire du CERN, Olivier Schneider explique l'importance du CERN pour la société suisse.
Auf der Suche nach dem 'sterilen' Neutrino
In wenigen Monaten startet am Fermilab bei Chicago (USA) ein aufsehenerregendes Experiment, mit dem Physiker abklären wollen, ob neben den drei bekannten Typen von Neutrinos ein vierter Typ besteht. Bemerkenswert an diesem Experiment ist auch die personelle Zusammensetzung der Kollaboration: Die rund 120 beteiligten Forscherinnen und Forscher stammen vorwiegend aus den USA, aber die wissenschaftliche Leitung des Experiments obliegt aber einem Schweizer, nämlich dem Berner Physikprofessor Michele Weber.
Kathmandu is calling
University education and academic excellence in research and teaching are taken for granted in affluent Western nations. We are used to having a broad spectrum of institutes in any possible field that exist in our part of the world. In developing countries though higher education is still a rare resource for many. This is also true for the field of particle physics, which is why representatives of the European Laboratory for Particle Physics CERN have launched a private initiative to take the seeds of this basic discipline to Nepal in order to let it grow there.
L'expérience BOSS
Seuls quatre pour cent de notre univers se composent de matière inconnue. En revanche, la physique moderne est convaincue que la majeure partie de l'univers se compose d'énergie noire. Personne ne peut encore vraiment expliquer ce qu'est cette énergie noire. Un astrophysicien de l'ETH de Lausanne (EPFL) fournit quelques indices pour une meilleure compréhension du phénomène : le jeune chercheur de 26 ans Timothée Delubac analyse des données du ciel étoilé qui devraient permettre une meilleure compréhension de l'énergie noire à l'avenir. Au cours de derniers mois, Delubac a acquis de nouvelles connaissances fascinantes dans le cadre de l'expérience BOSS.
Kosmische Strahlung aus noch unbekannter Quelle
Seit dem 19. Mai 2011 ist das Alpha Magnetic Spektrometer (AMS) auf der Internationalen Raumstation ISS in Betrieb. Das Hightech-Messgerät funkt seither ständig Messdaten über die kosmische Strahlung zur Erde. Nach knapp zwei Jahren macht das Experiment mit spektakulären Ergebnissen auf sich aufmerksam.
Débat Locarno
Cela en vaut-il vraiment la peine ? Des investissements de milliards de Franc pour découvrir une nouvelle particule ? Et ensuite ? Les gens vivent-ils vraiment mieux ? A quoi sert la physique ? Et quelles sont les conséquences pour la médecine ? C'est justement ces questions que la physicienne Martina Bucciantonio (35) et le médecin Franco Cavalli (71) ont abordé avec passion le 4 avril 2014 sous la direction du journaliste Gerhard Lob au lycée de Locarno. La discussion intitulé « Matière vivante ou matière morte » a eu lieu en présence de 50 lycéennes et lycéens de classe terminale.
Neutrino
Nous en sommes quasiment certains : les neutrinos muoniques peuvent se transformer en neutrinos tauiques. C'est ce qu'ont démontré des scientifiques de l'expérience OPERA à Gran Sasso (Italie,) dont un physicien de l'université de Berne, avec une précision insoupçonnée jusqu'à présent. Les chercheurs ont communiqué ce résultat à l'occasion d'un séminaire à Gran Sasso.
Gravitationswellen-Signal von Big Bang entdeckt
Einem internationalen Forscherteam ist mit dem Mikrowellenteleskop Bicep2 am Südpol der Nachweis von Gravitationswellen gelungen. Dies gaben die Wissenschaftler am Montag bekannt. Hält diese Nachricht einer unabhängigen Überprüfung stand, handelt es sich um eine der spektakulärsten Entdeckungen der modernen Physik. Damit würden erstmals die Gravitationswellen experimentell nachgewiesen, die Albert Einstein in seiner Relativitätstheorie vorausgesagt hatte. Im Interview erläutert die an der Universität Genf tätige Kosmologin Ruth Durrer die Hintergründe.
Protonentherapie
In der Schweiz studieren vergleichsweise wenig junge Frauen Physik. Anders in Italien, wo das Physikstudium für Frauen eine Selbstverständlichkeit darstellt. Kein Zufall daher, dass es mit Fabiola Gianotti eine italienische Physikerin war, die im Juli 2012 im Namen des ATLAS-Experiments am CERN die Entdeckung des Higgs-Teilchens bekanntgab. Auch Martina Bucciantonio ist italienische Physikerin, und auch sie arbeitet am CERN. Während sich die Nachwuchswissenschaftlerin zu Beginn ihrer Forscherkarriere vor allem mit grundlegenden Fragestellungen unter anderem in der Datenauswertung befasste, beschäftigt sie sich in der Doktorarbeit aktuell mit Fragen medizinischer Anwendungen. Am 4. April diskutiert Martina Bucciantonio an der Kantonsschule Locarno mit dem bekannten Krebsarzt Franco Cavalli zum Thema: „Lebendige Materie oder tote Materie – Forschen in der Medizin, Forschen in der Physik“ (geschlossene Veranstaltung). Bereits am 20. März findet um 16 Uhr ein Google-Hangout zum selben Thema statt.
Was die Teilchenphysik heute weiss
Dr. Hans Peter Beck, Privatdozent für Physik an der Universität Bern und Teilchenphysiker am Europäischen Labor für Teilchenphysik (CERN) in Genf gewährt in einem Interview mit der Webplattform Xecutives.net Einblick in das Weltbild der modernen Physik. Er erläutert die Hintergründe, die 2012 zur Entdeckung des Higgs-Teilchens führten, er spricht über die Geheimnisse der Dunklen Materie und erklärt aus seiner Sicht, was Physik und Mathematik verbindet.
Future Circular Collider
L'accélérateur de particules LHC (Large Hadron Collider) du CERN a permis la découverte du boson de Higgs en 2012 et après 20 ans d'exploitation, on attend d'autres découvertes décisives de la grande installation de recherche de Genève. Malgré tout, les physiciens travaillent déjà à la construction d'un nouvel accélérateur plus grand du nom de FCC qui devrait générer une plus grande énergie avec les collisions de particules. Stefan Antusch, professeur de Physique théorique à l'université de Bâle explique l'état et les objectifs du nouveau projet lors d'une entrevue.
Top-Quark
Sieht man vom Higgs-Teilchen ab, war das Top-Quark das letzte Elementarteilchen des heute gültigen Standardmodells, das experimentell nachgewiesen wurde. Dieser Nachweis gelang 1995 am Fermilab unweit von Chicago/USA. Wissenschaftlern dieser Forschungseinrichtung ist nun eine weitere Entdeckung rund um das Top-Quark gelungen: Sie haben einen neuen, sehr selten zu beobachtenden Weg experimentell nachgewiesen, auf dem das Top-Quark erzeugt werden kann.
Debatte Brugg
Teilchenphysikerinnen und Teilchenphysiker leisten mit ihrer Forschung einen Beitrag zum Verständnis der Welt. Sie tragen aber oft auch bei zur Weiterentwicklung der Wirtschaft durch innovative Produkte. Diesen Aspekt hat am 12. Februar 2014 eine Podiumsdebatte am Hightech Zentrum Aargau in Brugg beleuchtet, an der Roland Horisberger, ETH-Professor und Leiter der Hochenergiephysik am Paul Scherrer Institut in Villigen/AG, mit Wirtschaftsvertretern diskutierte. Am 23. April 2014 fand mit den Teilnehmern eine Internetdiskussion (Hangout) zum gleichen Thema statt (die Aufzeichnung finden Sie auf dieser Seite ganz unten). Podiumsgespräch und Hangout waren Veranstaltungen im Rahmen des vom Schweizerischen Nationalfonds geförderten Projekts 'Interactions'.
Accélérateur de protons
Recherche sur les matériaux, physique des particules, biologie moléculaire, archéologie : depuis 40 ans, le grand accélérateur de protons de l’Institut Paul Scherrer (PSI) rend possible de la recherche de pointe dans différents domaines. A ses débuts, il devait permettre d’élucider des questions d’actualité en physique des particules – et a pour cela produit des pions. Par la suite, les installations liées à l’accélérateur ont été élargies, et son faisceau de protons a dès lors aussi servi à produire des neutrons et des muons pour les expériences les plus diverses – souvent dans des domaines de recherche, auxquels personne n’avait pensé au moment de la construction du site. Aujourd’hui, il est possible d’y mener jusqu’à 20 expériences en même temps. Aujourd’hui, le grand accélérateur de protons du PSI fournit l’un des faisceaux de protons les plus performants au monde. Les expériences que les chercheurs et les ingénieurs du PSI y ont accumulées ont aussi servi de fondement à la mise en place de la protonthérapie, grâce à laquelle plusieurs milliers de patients atteints d’un cancer ont été traités avec succès.
Quantencomputer
Einzelne Ionen als Qubits eines zukünftigen Quantencomputers lassen sich sehr effizient mit Hilfe von Laserstrahlen kühlen und detektieren. Ein neu gestartetes Projekt möchte dieses Wissen nun auch zur Kühlung und Detektion einzelner (Anti-)Protonen nutzbar machen. Bei erfolgreicher Demonstration bietet sich eine hochinteressante Perspektive: die Anwendung der experimentellen Techniken zur Kühlung von Antiprotonen am BASE-Experiment am CERN in Genf.
Antiwasserstoff
Einem Forscherteam am Europäischen Labor für Teilchenphysik (CERN) in Genf ist es erstmals gelungen, einen Strahl aus Antiwasserstoff-Atomen herzustellen. Dies ist ein wichtiger Zwischenschritt hin zu einem besseren Verständnis von Antimaterie. Dieses Verständnis könnte eine Grundlage schaffen, damit Physiker in Zukunft einmal die grosse Frage beantworten können, warum unser Universum und wir Menschen aus Materie, nicht aber aus Antimaterie bestehen. Stefan Ulmer, der im Rahmen des ASACUSA-Experiments Antiwasserstoff untersucht, erläutert die aufsehenerregenden neuen Erkenntnisse.
Forschungssoziologie
Die österreichische Psychologin Dr. Clara Kulich (32) arbeitet an der Universität Genf und hat zusammen mit einem Kollegen untersucht, wie Forscherinnen und Forscher im Forschungszentrum CERN zusammenarbeiten. Die Resultate haben sie in Genf vorgestellt.
Chercheur des muons
Comment un physicien ou une physicienne trouve un fait dont la connaissance pose notre monde sur une nouvelle fondation ? Une réponse simple est : un travail de fond. Andreas Knecht, jeune chercheur suisse, le sait aussi. Il met actuellement en place une expérimentation à l'Institut Paul Scherrer (PSI) à Villigen dans le canton d'Aargau. Cette expérimentation pourrait bouleverser les fondements de notre image du monde. Toutefois, le physicien des particules doit encore faire preuve de patience en attendant des résultats. Beaucoup de patience. Au moins une décennie. (image: Andreas Knecht au sein de l'Institut Paul Scherrer. Foto: BV)
Concours du CERN
Le CERN, ce n’est pas que le Grand collisionneur de hadrons. Dans le cadre de ses activités de recherche et de développement, un grand nombre d’expériences, qui touchent à de multiples domaines d’étude, allant de la structure interne du proton aux mystères de l’antimatière, sont réalisées grâce à des lignes de faisceau avec cibles fixes. En 2014, à l’occasion de son 60e anniversaire, le CERN va mettre une ligne de faisceau et toutes ses installations à la disposition d’un groupe d’élèves du secondaire, pour leur permettre de mener à bien l’expérience de leur choix. Ces chercheurs en herbe seront encadrés par des physiciens, des ingénieurs et des spécialistes de l’acquisition et de l’analyse de données. Comme pour toutes les expériences du CERN, le temps de faisceau sera attribué selon la valeur scientifique de la proposition.
