Offline DQM Shifts at the CMS Center
posted by: dberry
Two weeks ago I spent a large amount of my time in the Meyrin CMS Center. The CMS Center is a centrally located control center where a lot of offline shifters monitor detector components. Shifters there monitoring varies sub-detectors; such as the the strip tracker, the pixel detector, and the muon systems. I was there for a week monitoring the data from the early collisions.
The Offline DQM shift consists of monitoring most of the detector sub-components and entering their status into an online database called the run registry. Each sub-detector, Castor, Cathode Strip Chambers, Drift Chambers, ECAL, HCAL, HLT, L1 Trigger, Pixel Detector, RPC, and Strip Tracker, and physics object, EGamma, JetMET, Muon, and tracker, must be certified by the offline DQM shifter. Below is an image of the tools that I used on the DQM offline shifts to monitor the detector performance.
The DQM shift start at 07:00, 2 hours earlier then the other shifts at the Meyrin center, so I got the CMS center all to myself.
