In the triangle Uni Zurich-PSI-CERN

Anyone who studies physics at the University of Zurich knows Lea Caminada for her lectures. Most of the time, however, you will not find the particle physicist on the Irchel campus, but at the Paul Scherrer Institute (PSI) in Villigen in the canton of Aargau doing research. There, the 36-year-old scientist develops sophisticated measuring instruments, which are then used at CERN for cutting-edge research. In a questionnaire, Lea Caminada gives an insight into her everyday life as an experimental physicist.

OPERA collaboration presents its final results on neutrino oscillations.

OPERA collaboration reports the observation of a total of 10 candidate events for a muon to tau-neutrino conversion, in what are the very final results of the experiment.

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.
Stefano Marzari, a Mechanical engineer trained at the EIF (Engineering School of Fribourg), helped to set up the CERN-MEDICIS facility. In the picture, Marzari shows the first 155Tb isotope plate produced by CERN-MEDICIS on December 11, 2017. 155Tb has a half-life period of around five days; the radioactive emissions of the sample produced in December is almost completely finished.

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.

One focus point is the multi-messenger astronomy

On 9 January 2018 the Astroparticle Physics European Consortium (APPEC) will officially launch its new Strategy 2017-2026 in Brussels. The strategy is addressing the main scientific issues of astroparticle physics in the upcoming decade. Teresa Montaruli – physics professor at the University of Geneva and the representative of the Swiss National Science Foundation (SNF) and of the CHIPP association of professors in the APPEC General Assembly – gives an outlook on the key messages of the new strategy.
