Subject: aida10 troubleshooting 
aida10 has no ASIC events when running without pulser

DSSD ribbon cable was replaced, no change

29.01.2020 - change AIDA half adapter board, no change

Swapped HV (braid) from aida10 to aida12 - no change in leakage current, now testing data...
 Looks the same (no data) fig 2

Very hot channel in aida08 as well:
 - Channel 104 in histogram Stat = 4.7.L  fig 1

Change FEE64 card?
Any other checks possible?

31.01.2020:

Installed new FEE64 card aida10: d8:80:39:41:ba:89
Updated dhcpd.conf
System boots OK.
returned bias ground to aida10 for symmetry reasons
Firmware updated from 0x12110103 to 0x18430701

Left recording alpha data over the weekend:
See stats in fig 3

DSSD 1 and 2 look excellent (one broken strip in DSSd 1)?

aida10 still no counts?
aida09 looks very... weird as well?
aida11 and aida12 seem ok?

Detector fault?
