Minutes of the Trigger Operation Meeting (21st August, 2007)

Operations

• Sunday swing shift: email for GLT timing plot bin 1 (IFT) low by ~1tick. Did not appear so bad in L1 LiveFastMon file so possibly an artifact of low statistics. Disappeared in next run.
• Paged Monday AM for ODF damage - MPIC spurious interrupt error in ROM log file so instructed pilot to power-cycle crate. This is the first time we've seen this error in a while - frequency seems to be falling off after a busy July.
• Please take a look at the slides for the ~monthly TRG status report for tomorrow's 3.45 meeting.

EMT

• Jim's question about the EMT calibration remains - should look at code to check if it always returns "success".

L3

• Validation of Arik's code changes are in progress.
  • In data: looking for losses in single/double track lines. Also checking lines used to calculate hadronic ratio so that lumi ratio does not change when the code is introduced.
    -> Done! changes small.
  • In MC: Ensure we can adequately simulate old data- the old track-finding should not change with the code modifications alone!
• Can turn code on this month if we know lumi is not affected.

Data Quality and Monitoring

• All is well with the data so far. Other work is still in progress.

Trigger Configuration

• Study is still on-going. See status page for up-to-date information.
• The 1E line could be put in this week. Still need to check whether it will affect other open lines - e.g. Bhabha rates could blow up.
