CMS Status as of 06 May 2020
During the early months of 2020, as the COVID-19 threat increased, CMS activity was adapted to gradually transfer responsibility to locally resident collaborators.

Planning for years of luminosity measurements with BRIL
When the LHC is sending billions of protons at each other millions of times per second, it’s important to know just how many of them actually are colliding, both so that the LHC can optimize its operations to produce the most collisions possible, and as an important input to nearly any measurement that will be…

New precision timing detector for the CMS HL-LHC upgrade
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. In order to achieve such high luminosity, the LHC is going to use much more densely packed bunches of protons to…

The ECAL prepares to extract the super-modules from CMS
The CMS electromagnetic calorimeter (ECAL) measures the energy of electrons and photons produced in the LHC collisions with extreme precision.

Preparations for an upgrade of the heart of CMS
The CMS detector is going through multiple maintenance works during the LHC Long Shutdown 2 (LS2), the first year of which is approaching its end.

HCAL Completes Phase 1 Upgrades on the CMS Detector
With the connection of the final cable on October 4, CMS completed the installation of new on-detector electronics for the Hadron Calorimeter (HCAL) barrel detector.

CMS Continues to Shine with New GEMs
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.

A NEW ERA IN CALORIMETRY
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.

The start of something new
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.

CMS and the machine learning at the forefront of data management
Managing the amount of data from the Large Hadron Collider (LHC) collisions is a major challenge for CMS physicists.
