CERN Accelerating science

The CMS magnet, one of the largest superconducting magnets in the world, with the largest stored energy, has been warmed up in April-May 2020 in order to perform an intervention on the vacuum pumping system.

Soon after 2027, the LHC will enter the high luminosity era, known as HL-LHC, during which it is expected to deliver about 20 times more data than delivered up the end of Run 2.

2019 is approaching its end with it the first year of the LHC Long Shutdown 2 (LS2),a break that focuses on the upgrade and maintenance of the LHC.

Early one morning, residents of the Pathum Wan District of Bangkok were greeted to the rare spectacle of dozens of physicists in formal attire walking the streets of Bangkok on their way to meet Her Royal Highness Princess Maha Chakri Sirindhorn of Thailand.

The CMS electromagnetic calorimeter (ECAL) measures the energy of electrons and photons produced in the LHC collisions with extreme precision.

The 2019 edition of the International Conference on Computing in High Energy and Nuclear Physics (CHEP, chep2019.org) was held on 4–8 November in Adelaide (South Australia).

The CMS collaboration presented over ten brand-new results in the latest installment of the Quark Matter conference, one of the largest conferences in the field of heavy-ion physics.

The high-granularity calorimeter (HGCAL) is a major upgrade of CMS, and is necessary to maintain excellent calorimetric performance in the endcaps during HL-LHC operations.

Congratulations to five CMS scientists, Tulika Bose, Yuri Gershtein, Andrei Gritsan, George Wei-Shu Hou and Markus Klute, who were elected as American Physical Society (APS) Fellows in 2019 for their excepti

The CMS Gas Electron Multiplier (GEM) subsystem will form an extra layer of detectors, along with the Cathode Strip Chambers (CSC) layers, closest to the beam.
