Late Night with CMS
posted by: dberry
Over the past couple of weeks I have been on shift with the CMS ECAL. These shifts consist of monitoring the ECAL while it records data. The person on shift makes sure everything is working properly, and if something breaks, they inform the appropriate expert. When a person is on shift there are a lot a monitoring tools they can look at. Most of a shifter’s time is spent monitoring the DCS controller, the ECAL DAQ, the XMAS monitor, and the DQM. The DCS controller monitors the voltages, currents, and temperatures of the detector. The ECAL DAQ system reads the data from the ECAL. The XMAS tree monitor displays information about the ECAL DAQ. The DQM monitors the data as it is read from the detector. Below is an image of what I look at on shift.
Inside the control room there are three large monitors. One which displays general information about the run, another has an event display, and a third which displays the beam status (image below).
