15:00 Platform in, biasing detector. Temp OK Attachment 1. test - Pulser OFF.
Rates somewhat worse than last night - probable contact on grounding of snout. Attachment 3.
Histograms okay, some FEE64s now have hot channels. Attachment 2.
9/16 aidas < 20kHz - max rate 162k
18:06 - powering down detector for the weekend. Overall system is fine, some channels (hot channels) definitely picked up noise, but condition is overall stable over three hours. See atachments 4-5.
TO-DO (kicking the can down the road):
- Some work to do on noise, but we might have to accept the situation as it currently is.
- Implement bPlast trigger scheme. Set bPlast thresholds, get bPlast current draw undercontrol - observe AIDA noise.
- Try different grounding configuration:
- Grounding drain wires to frame. Observe AIDA conditions.
- Reconnect 4V out to R&SRMP4040 common ground with PN 300 PSU as well. Observe AIDA conditions.
