Remount snout in S4 (photos to come) 
Alignment with DEGAS OK but a bit short...  DEGAS platform will be brought 31 mm closer to AIDA by rail adjustment

Can mount bPlas booster boards on old ITEM frames and also partly on AIDA snout (isolated)

-

Reconnect all adapter boards and grounds, bias AIDA...

HV OK. We still have a light leak at the snout endcap. "Fixed" with sheet for now

HV leakage currents figure 1

Start AIDA DAQ and check rates.. all seem OK. aida07 is very noisy other p+n good
Notice some issues in aida04, check and ribbon cable slightly loose on one side of adapter
No change to other FEEs.
Aida07 was inspected but nothing obviously wrong

Rates figure 2
Rate spectra figure 3
Wavesform figures 4 (p+n), 5 (n+n)
Pulser peak withs
 p+n figure 6, width ~  70 channels (50 keV)
 n+n figure 7, width ~ 570 channels (400 keV)

n.b. double peak in aida14 is an artifact from an uncleared histogram

DSSDs debiased to allow work on bPlas cabling without tripping DSSDs
