Probably this is from background as tracking on the SBS side wasn't done using the calorimeter constraints that time. | **The very first day of the GEM commissioning we got more confused as we got some tracks in the SBS GEMs using this latency.

Contents
Near term work plan
- Thoughts on special run requests during GEn:
- Luminosity studies
- Full readout studies for negative pulse studies
- HV efficiency scans with beam
Update on BB GEMs
- HV efficiency scan
Update on layers for GEn-RP
- Alignment/latency/tracking issues
- SBS GEM latency was incorrectly set at the beginning of the experiment, by using the latency we used for the cosmic paddle trigger - 76
- The very first day of the GEM commissioning we got more confused as we got some tracks in the SBS GEMs using this latency. Probably this is from background as tracking on the SBS side wasn't done using the calorimeter constraints that time.
- But when the calorimeter constraints were turned on, we got just only 10's of tracks for like 150K trigger events.
- Had a discussion with Alex yesterday and we agreed starting around the BB GEM latency (112 now) and scanning around it would be a good place to start
- BB
- gas
Update monitoring with new GEMs in GEn-RP
- replay times with tracking
