Types of Shifts Ø Sub-detector Shifts for ECAL, RPC, HCAL, Tracker, Castor & Pixels Ø Central Shifts: DQM, DAQ, DCS & Trigger Ø Expert On-Call Shifts Pre-requisites for ECAL Sub-detector Shifts ü Requirement to take Safety Courses Levels (1, 2, 3 & 4 C) for access to CMSCR & CMS-USC ü Need to Study Shift Tutorial ü Training Shifts to be taken ü Subscription for Shifts through Shift Selection tool 2

Shifters Duties q Read the Run Field Manager’s Current Plan q Fill the Run Checklist for every run (Run Time > 15 Minutes) q Write an E-Log for any problems or crashes q Monitoring FED Status for all FEDs participating in Global Run q Monitor Central DQM & ECAL DQM for Status of various Parameters q Monitor Beam Status and give feedback to LHC-CR q Take Local Runs incase ECAL (EB + EE) or Preshower (ES) fails q Write Shift Summary q In rare cases, Take control of DCS from central DCS 3
