11.15 - S4 is currently closed no access

If access possible (should be) plan is

Re-attach ribbon cable braids
Re-attach DSSSD middle wafer rear g/r (LK3)
Re-attach DSSSD ground (LK2?)

See difference in rates, expectation is braid should restore most p+n rates

Once status quo ante achieved explore ASIC settings to identify preamp feedback and shaping time options to stabilise preamp output and optimise signal:noise.

aida12 Peak width =    78.51
aida02 Peak width =   480.90

No major change, FEES 1-8 are all noisy and FEES 9-16 are quiet
aida01, aida05 waveforms very noticably bad (100 kHz), aida03, aida07 waveforms seem OK


16.45 - Attach LK2, LK4 jumpers to all FEEs (field plane grounding)
No significant changes

aida12 Peak width =    87.87
aida02 Peak width =   504.41

The correlation between high 'ADC data item' rate and the noise observed on the corresponding 1.8.W spectrum is not clear *except* for aida01 & aida05 - see also attachments 34-35

ADC data item stats - attachment 36

DSSSD bias & leakage current OK - attachment 37

FEE64 temperatures OK - attachment 38

all system wide checks OK *except aida11 clock fail status 6
