Operations

  • Run Coordinators want to know when pi0pi0 filter will be ready to be implimented. They want to decide when to take off-peak data.
  • Conclusion: since we will take off-peak data at the end of the run again, we'll take off-peak data with current trigger configurations. We have to emulate last two trigger configurations already, don't want to add another different configuration.

EMT

  • Calibration failed. Updated reference file. Calibration is fine.

DCT

GLT

L3

DQM

Trickle injection monitoring

Trigger Configuration

  • L1 rate at ~7000 Hz is a clear wall (dead time vs. L1 rate for a week, as of today).
  • We'll apply tigher cuts to reduce L3 rates (which is reaching a limit) including SingleGammaFilters with angular cuts.
  • L1 trigger modification plan: 2M1G and M*1G0B will replace two 1zxx lines.
  • All these changes will be in after off-peak runs. (The off-peak runs will take about 1.5 days.)

AOB

  • Rainer installed a new Level 3 EPICS server (L3TPcaServer) that provides hadronic A and B ratios and their errors sampled over 10s, 1min and 5min intervals. The channel names are L3T:HADA:1MIN and similar. Sunday Day shift.
