At the Physics Institute at the University of Bern, Armin Fehr and his colleagues have built the future 'Inner Tracker' of the ATLAS detector on a 1 to 1 scale. In the tube on the left, the proton-proton collisions take place. The dark red box shows one of the regions where the Optoboards will be located.

Every second fifty terabits of data

From 2026, the performance of the large-scale experiments at the European particle physics laboratory, CERN, in Geneva will be significantly increased. The preliminary work for the upgrade of the large particle accelerator LHC and the associated detectors is currently in full swing. An important contribution is made by the University of Bern, where doctoral student Armin Fehr (26) and his colleagues are working on a component for the ATLAS detector. This component will enable the read-out of the greatly increased data rates from 2026 onwards.

The Innovation Park “PARK INNOVAARE” in Villigen (AG) supports start-up companies in the field of accelerator technology.

CERN in Geneva is the leading particle physics laboratory worldwide. Large particle accelerators based on the most innovative technologies are used there for fundamental research. One year ago, the innovation park “PARK INNOVAARE” in Villigen (AG) launched, together with CERN, the BIC of CERN program: it supports start-ups and high-tech micro-companies using CERN technologies for commercial applications. These days the second call for proposals has started.

The LHCb collaboration at CERN has discovered a type of CP violation unobserved so far

The LHCb collaboration at CERN has seen, for the first time, the matter–antimatter asymmetry known as CP violation in a so-called D0 meson. LHCb is one of the four large experiments performed at the Large Hadron Collider (LHC) with Swiss participation of Ecole polytechnique fédérale de Lausanne (EPFL) and University of Zurich.

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.

The FCC provides science for almost a century

In spring 2020 the European particle physics community will decide on a new European Strategy highlighting the strategic long-term goals in this important field of fundamental research. In December 2018 Swiss scientists – organized by the Swiss Institute of Particle Physics / CHIPP – have formulated their input to the new European Strategy. Günther Dissertori – professor at ETH Zurich, member of the CHIPP Executive Board and incoming Scientific Delegate of Switzerland in the CERN Council – explains the main points of the Swiss strategic input.

James Sinclair designs a novel neutrino detector at the University of Bern

Neutrinos are electrically neutral and very light elementary particles, which interact only weakly with other matter and are therefore difficult to observe. From 2025, a new neutrino experiment in the US aims contributing to a better understanding of the neutrinos. At the University of Bern physicists are currently working on the prototype for a detector to be used in the upcoming experiment.

PiA - Physics in Advent: still 24 experiments until Christmas

PiA offers 24 entertaining physics experiments to do yourself again this year. Due to the great interest from abroad, physics will be available in English during Advent, just like last year.

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.
