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.
