1. ECAL Shift Duty: A Beginners Guide By Pourus Mehta

2. 2 Types of Shifts  Sub-detector Shifts for ECAL, RPC, HCAL, Tracker, Castor & Pixels  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- CR & CMS-USC Need to Study Shift Tutorial Training Shifts to be taken Subscription for Shifts through Shift Selection tool

3. 3 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
