FASER Detector Installation

During March the FASER detector was successfully installed into the LHC complex. FASER, a new small LHC experiment, designed to search for light, weakly interacting new particles in the LHC collisions was proposed in 2017, and after review by the…

The commissioning and installation of the new ALICE ITS

The Inner Tracking System (ITS) is the innermost detector of the ALICE central barrel. It consists of seven cylindrical layers all equipped with Monolithic Active Pixel Sensors (MAPS) named ALPIDE (ALice PIxel DEtector). The ITS allows track ing…

Pinning down the muon (g-2) anomaly at the CERN SPS

The Dirac equation predicts the muon gyromagnetic ratio g=2. Loop effects from quantum field theory lead to a small deviation from this value, parameterized by the so called anomalous magnetic moment which is defined as aμ=(g-2)/2. The difference…

Aligning the ATLAS muon spectrometer

If you visit the ATLAS experimental cavern, the first thing you’ll see is the muon spectrometer: several thousand chambers that make up the outermost layer of the experiment (see image above). As muons fly out of the collision point, their tracks…

DT group publishes 2020 annual report

Last week, CERN's EP-DT group published their annual report for 2020; a detailed accound of the group activities at CERN conducted over the year in collaboration with the LHC and non-LHC experimental groups along with their academic and industrial…

ISOLDE determines precise nuclear moments by devising novel experimental technique

Nuclear quadrupole moments (Q), a measure of charge asymmetry in nuclei, are experimentally accessible via the quadrupole interaction frequency νQ=eQVzz/h. To extract Q from this information one needs to knowVzz, the electric-field gradient at the…
