Kept largely the same settings at the entry https://elog.ph.ed.ac.uk/AIDA/4
Same ASIC settings
Emco used to provide HV
HV+ --> nnaida11 & nnaida12 (p+n strips, -ve pulser input)
HV- --> nnaida13 & nnaida14 (n+n strips, +ve pulser input)
Stat spectra look roughly the same as those included in the above entry.
Now see large peak around ~32k, present in all spectra to some degree. Mostly larger than corresponding pulser peak.
Power cycled several times, reloaded+checked ASIC settings etc., no change. Any ideas? Have I forgotten something?
The ASIC events stats rate is also very high on nnaida11,12,14. 13 is high but not excessively.
Pulser peak shows double peaking on all ASIC channels with individual widths of ~250ch and total width of ~500ch.
Noise peak has width ~50ch. This has reduced somewhat (was ~100s ch) with my last power cycle, but clearly still not gone.
I'll try again in the morning, but if no change will proceed with the shaping time tests with the spectra as they are.
