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
Online
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.
