CMS has just recorded the first collisions with stable beams at a world-record collision energy of 8 TeV[1].
CMS took good quality data with all sub-detectors working well.
The LHC fill lasted for 1h34min and the "pile-up" at the beginning of the…
The first 7 TeV (3.5 TeV + 3.5 TeV) collisions took place on 30th March 2010, starting around 1pm local (Geneva) time and lasting for about 3.5 hours. Read the CERN Press Release here.
The CMS detector and its collaborators are all eagerly awaiting…
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…
