Conclusions
ADC data item stats -> 300-400k
n+n 1.8.W spectra show large signal excursions
p+n 1.8.W spectra for biased Si wafers OK - unbiased Si wafers show large signal excursions
DSSSD#1 leakage currents 1.850+2.220+1.990=6.06uA cf. 5.095uA with all 3 wafers biased
DSSSD#2 leakage currents 1.510+1.580+2.350=5.44uA cf. 5.235uA
Right wafer (looking upstream)
Bias(V) -20 -40 -60 -80 -100
DSSSD#1 I_L(uA) -1.135 -1.475 -1.645 -1.750 -1.805
DSSSD#2 I_l(uA) -1.625 -2.020 -2.205 -2.320 -2.360
Middle wafer (looking upstream)
Bias(V) -20 -40 -60 -80 -100
DSSSD#1 I_L(uA) -1.540 -1.870 -2.035 -2.150 -2.210
DSSSD#2 I_l(uA) -0.985 -1.285 -1.465 -1.575 -1.615
Left wafer (looking upstream)
Bias(V) -20 -40 -60 -80 -100
DSSSD#1 I_L(uA) -0.735 -0.915 -1.005 -1.080 -1.110
DSSSD#2 I_l(uA) -0.865 -1.205 -1.400 -1.510 -1.560
Bias versus leakage cuurent characteristic of each wafer of each DSSSD indicates diode behaviour.
Note LK1 not fitted - presumably LK3 of mid/top p+n FEE64 adaptor PCBs (aida01 and aida05) connecting n+n bias to gnd is sufficient to establish circuit.

Noise observed for asics #1 & #2 of aida02 consistent with no cable attached - confirmed by visual inspection - ribbon cable disconnected from Samtec header of adaptor PCB
To Do list
1) re-connect ribbon cable to aida02 adaptor PCB
2) good quality ground to snout - use screws at inter-stage
3) install heavy duty grounds
4) ...

Try power cycle as system ground changed significantly now
Try to reattach aida04 TTY connector - still wrong
Archive old tty logs (ttyUSB*) to zip and delete them, makes easier to track startup
Attachment 12 - per FEE64 rate spectra - slow comparator 0xa
No major difference, aida01 quieter than before
aida05 has some missing channels - loose ERNI?
Attachements 13 & 14 - Waveforms
Temporarily raise to 0x64 and test merger for DTAS synchro test later... all works good to MBS
Change NETVAR MERGE.LinksAvailable to 8
Notice one copper screw touching aluminium, add some kapton tape behind it to isolate it. No difference
Voltage diff between aida02,aida06 < 1 mV
Voltage diff between copper bars < 0.5 mV (but not 0)
A comment from DTAS people that they observed a large increase in noise recently - perhaps from accelerator
May indicate current power/gronud oddities?
Attachment 15 - Rates at 0x1f (= 310 keV)
DSSSD#1 reasonable (aida04 a bit bad), but mostly just pulser (25 Hz)
DSSSD#2 much worse esp. p+n sides (aida05, aida07)
ERNI connectors pushed in and feel fully in |
