The installation of a new prototype of CMS muon chambers was completed last December. With these installations, the CMS detector is taking further steps towards the HL-LHC era at CERN.
With the future High Luminosity Large Hadron…
The Large Hadron Collider (LHC) has been providing particle collisions at larger and larger luminosities over the years, thanks to a series of upgrades. However, the most anticipated upgrade has yet to come: the High Luminosity LHC (HL-LHC). Here…
Despite the rather challenging circumstances of the COVID-19 pandemic, the CMS GEM (Gas Electron Multiplier) team has been working against all odds to complete the installation of the very first GEM station (GE1/1) in CMS. With the completion of one…
Since late May, with the incremental re-opening of CERN’s facilities, members of the CMS GEM project have been hard at work restarting the laboratory activities in preparation for the continued efforts towards the GE1/1 chambers installation. Made…
The Compact Muon Solenoid (CMS) Muon System is undergoing major upgrades during Long Shutdown 2 (LS2), preparing for the High Luminosity LHC (HL-LHC). The Large Hadron Collider will be upgraded to significantly increase the luminosity (frequency of…
On July 25th, 2019, the very first GEM superchambers were installed into the CMS YE- endcap as part of the newest CMS muon subsystem, GE1/1. And while this was a fantastic accomplishment worth celebrating, it was only the beginning of the story.…
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. The GEM's ability to cope with a very high particle rate will greatly improve…
After the LHC was shut down in December 2018 following the successful completion of RUN 2 operation, CMS is undergoing an intensive upgrade and maintenance program during the current two-year break (“Long Shutdown 2” or LS2) in order to ensure an…
During LS2, CMS will install 144 additional muon detector modules specially designed to detect particles produced in the very forward region.
For the CMS experiment, Long Shutdown 2 (LS2) is like very prolonged open heart surgery. The…
