Shift Tasks Overview

When Arriving on Shift

Please come to the ATLAS Control Room 10-15 minutes before the actual start of your shift. Check with the previous shifter

  • What are the status and the current conditions of the run ?
  • What is the Atlas run plan for the day (can be checked also from the Muon Whiteboard or RunCom tool)
  • Are there any special problems ?
  • What calibration runs have been done already by the previous shifter ?

Then make sure you

  • Close any not needed windows and applications on the muon desk.
  • Sign in to the RunCom tool with your name and complete the sing-in checklist. Only post it to elog when asked to do so if there were anomalies.
  • Setup the Muon Desk and make sure all required tools and overview panels are open and arranged such that you can monitor all muon sub-detectors.
  • Log in to elog and read the previous shifter's shift summary and other recent muon items
  • Log in to the the DCS FSM and DCS Alarm Screen Panels
  • Open the Muon Whiteboard page and check it for special instructions and known problems.
    If the whiteboard is already open make sure you refresh the page to pick up any changes!

During the Shift

During a Run

In addition the the tasks listed above,

  • Monitor the TGC Status Panel, there should not be any BUSY RODs or abandoned Star Switches (SSWs)
  • Monitor the RPC Rates and Busy Panel, there should be max. 5 red (auto-killed) towers and no abnormal rates
  • Monitor MDTs for Dropped Chambers, recover any dropped chambers manually.
  • Monitor the DAQ MRS Messages, react on any (recurring) errors
  • Check DQMF half an hour after a run was started and regularly once stable beams is achieved, it should be green . Report anomalies.
  • Check OHP half an hour after a run was started and regularly once stable beams is achieved.
  • Use MDT GnaMon to check MDT occupancies half an hour after a run was started and regularly once stable beams is achieved. Report anomalies.
  • Once Stable breams is achieved, check the Muon Calibration Stream
  • Regularly Update the Shift Online DQ flags up to the current luminosity block.

During Calibration Periods

In any calibration period announced by the shift leader, please do

  • the 3 TGC calibration runs, as described here
  • a CCS pedestal run, as described here
  • any special calibration task listed on the muon whiteboard

If you are short on time, you can skip the CSC pedestal run if it was done already that day.

At the End of your Shift

At the end of your shift please

  • Fill in the muon shift summary, using the provided template which can be found here, and post it to elog using the Message Type Shift Summary --> Muons.
  • Inform your replacement shifter on runs taken during your shift, the current status and any problems encountered during your shift.
  • Do not leave before your replacement arrives.
  • If your replacement is late by more than 20 minutes, inform the shift leader and call the muon shift phone number to arrange for somebody else.
  • If your shift was the 7am to 15pm one, attend the daily muon data quality meeting at 15:10h in building 3150 (barracks to the left of the entrance/gate to P1)
