Central Shifts: DQM, DAQ, DCS & Trigger

Expert On-Call Shifts

Pre-requisites for ECAL Sub-detector Shifts

Requirement to take Safety Courses Levels (1, 2, 3 & 4C) for access to CMS-

Shifters Duties

Read the Run Field Manager’s Current Plan

Fill the Run Checklist for every run (Run Time > 15 Minutes)

Write an E-Log for any problems or crashes

Monitoring FED Status for all FEDs participating in Global Run

Monitor Central DQM & ECAL DQM for Status of various Parameters

Monitor Beam Status and give feedback to LHC-CR

Take Local Runs incase ECAL (EB + EE) or Preshower (ES) fails

Write Shift Summary

In rare cases, Take control of DCS from central DCS
