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. The beginning of 2019 saw the CMS Tracker Pixel detector extraction that is now stored in a clean room…

The LHC circulates protons inside its beam-pipes not in a continuous stream but in several very closely packed bunches. In order to maximise the probability of the tiny protons colliding with one another, the LHC tries to pack as many protons as it…

The Year-End Technical Stop or YETS, when the LHC takes its annual break, seemed like a quiet time to those outside CERN. After all, there were no collisions taking place and the CMS detector was not operating 24-hours-a-day, seven-days-a-week.…

Christophe Delaere, from the Université catholique de Louvain in Belgium, has been with CMS for five years. Christophe works on the Tracker, the sub-detector that traces the path of charged particles that are formed in collisions at the LHC. Watch…

At the turn of the year, the Tracker management baton passed from GianMario Bilei (picture, at right) to Karl Aaron Gill (picture, at left), who will be the Tracker Project Manager for 2011-2012. GianMario's two-year term started on January 1st,…

The Tracker held its first "Week" outside CERN. The meeting took place in Hotel Hermitage, a nice seaside resort in the small village of La Biodola on the Elba Island (Italy), from 23 to 28 of May 2010. It was a full-immersion 5-day workshop. The…

As the LHC has delivered the first collisions and the first CMS physics paper with collision data is published, in a memorable ceremony Awards for Outstanding Achievements in the Construction of the CMS detector were given to 100 collaborators. 21…

On March 30th at 12.58 LHC delivered to CMS for the first time 7 TeV Ecm collisions. CMS and the Tracker were fully operational and collected about 210.000 Minimum Bias events in ~ 2 hours during the first fill. Everything worked very well, the…

Today LHC delivered to CMS a total of about 5 hours of clean collisions and we have recorded about 11000 min bias BSC triggers. The quality of the data produced and the performance of the Tracker together with the exceptional speed with which we…

This morning between 8:20 and 8:50 for the first time the full Tracker (Strips and Pixel) was turned ON and successfully collected data in Global run with a quiet single beam running in LHC. This is a major achievement. Everything seems all right…

Only TOB was turned ON today after LHC Opearation declared stable beams for a while. Below is a 900 GeV p-p collision event seen by the TOB in Run 122314, Evt 8605569.
