L1Calo On-call Expert Responsibilities

Expert on-call duties are still being defined and could be changed. Some of these duties will change/expand with beam, and we may choose that some of them are transferred to an (off-site) offline shifter. The expert should try to keep these pages up-to-date.

Before you are on-call

  • Subscribe to the Level-1 e-log, at least for the week of your on-call.
  • Familiarize yourself with known problems.
  • When you receive the on-call phone check that call forwarding is disabled.

During on-call

  • Make sure you mobile phone is on and in range at all times, and ideally that you can get to Point 1 if necessary.
  • Go to the daily run meeting to get up-to-date information on the programme, and how it might affect L1Calo. Also attend the weekly run meeting.
  • Read the e-log and follow up any items of relevance to L1Calo.
  • Check trigger rates regularly - most easily done through Martin's rate plots.
    • For cosmics check that J5 ~5 Hz, TAU5 ~4 Hz, EM3 ~0.5 Hz and FJ3 ~very small.
  • At least once a day check the online histograms, and launch a spy GUI to check the L1Calo status tabs - nothing should be red.
  • Check the Tier0 Data Quality histograms.
  • Check through the list of recent ATLAS runs through the run summary page. For each run:
    • Check that L1Calo was included,
    • Check at least the main triggers (again J5, TAU5, EM3, FJ3) were enabled (preferably unprescaled) and that the number of events for that run was reasonable given the rates and length of run.
    • Set the offline DQ flag.

After on-call

  • Pass-on the on-call phone to your successor after the 9AM run meeting on your final day.
