Remember that 'ADC calibration' refers to the setup of the fast serial output of the AD9222 Octal, 50MSPS, 14 bit ADC which generates the waveforms - if the FEE64 is unable to calibrate all that happens is that you will not be able to see preamp output waveforms. Energy spectra will work regardless as they use a different ADC.

Inspection of side FEEs (2,6,4,8) and possible grounding improvements:

- all screws and nuts for copper connections were tightenedFee

- FEE 6 was isolated from the copper connection grounding FEE2 with insulating tape (attachment 1)

- A piece of tape was found below FEE6 (attachments 2,3) --> shall this be removed?

 

Bias and power on of FEES, preparation of two settings with lower thresholds:

- note: cannot calibrate ADC of aida15 even after trying multiple times (?)

- 500-keV thresholds settings saved as EXPERIMENTS/AIDA/2025Oct29-09.49.01

- 200-keV thresholds settings saved as EXPERIMENTS/AIDA/2025Oct29-09.55.31
