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.

    DQM = Data Quality Monitoring?

    Yes, DQM does stand for Data Quality Monitoring.

    What would happen if you didn’t check the plots?

    Doug,

    You said and your photo shows that there was no one else in the Meyrin CMS Center when you took the photo at 7am. I’m surprised the night shift wasn’t still there? Was the beam off the night before? The CMS Center looks like a comfortable and well-equipped area to work.

    The Meyrin CMS Center is only for offline monitoring currently. That means all the main shifts still take place at point 5. Offline shifts can be preformed remotely from FNAL, DESY, or sometimes just a laptop. This means that there is little need for offline shifters to come into the CMS Center. Eventually sub-detector shifters and central shifters may be moved to the CMS Center, but until then, the majority of the shifters will be at P5.
