Contents
Near term work plan (all)
- Installation of HV dividers on BB: April 18 for 3 weeks, upgraded dividers on back tracker and active on front 3 layers
Update on BB GEMs(Sean, Ezekiel, Holly, Anu)
- We cannot use pedestal plots as indicators of APVs that are disconnected (see email).
- Negative signal tracking study
- HALOG with all plots - https://logbooks.jlab.org/entry/3986717
Update on UVa GEM layers for GEn-RP (Anu, John, Thir)
- Still having issues with "gaps" or "dead zones" on inline layers
- Possible trigger issues?? Need to step through the system and scope/check It out
- Need to get as many GEMs/APVs up as possible to rule out any effects due to tracking.
- Connection issues with APVs on Inline Layer 3 - G3
- We slid the layer out and re-attached/assessed the connection of the 12-slot
- Replaced the APV on Inline Layer 4 G0 12-slot. Inline Layer 3 and 4 are on the same frame.
Update on INFN GEM layers for GEn-RP (Ezekiel, Holly, Evaristo)
- HV divider upgrade for INFN GEMs
- First test of parallel divider
- Cosmic Run 1943
- Cosmic Run 1974
DAQ updates (Ben, Bryan, Alex)
- schematic of setup?
- FIR filter?
- Update on: need 2 DC working in Hall A
