- AIDA FEE64 PSU cabling - see attachment 18

Currently

PSU #1 1-3, 2-4, 9-5, 15-12
PSU #2 14-7, 6-8, 10-13, 11-16

Should be changed to

PSU #1 1-3, 2-4, 9-15, 5-12
PSU #2 14-7, 6-8, 10-11, 13-16


- AIDA snout mount to support frame - attachments 19 & 21
LHS ( looking downstream ) incorrect, RHS OK

- LKs
LK1 fitted aida02, aida04, aida06, aida08
LK3 fitted aida03, aida07, aida01, aida14


Significant gaps in snout ( i.e. possible light leaks ) where bPlas cabling exits snout - attachments 20 & 22

bPlas driver PCBs removed 
bPlas ribbon cables, drain wires and Lemo 00.250 cabling disconnected - some cabling/drain wires touching snout etc


15.15 Adjust bPlas ribbon cables/drain wires/Lemo cables to ensure that none are touching snout or AIDA support frame - significant improvement

      DSSSD bias & leakage current OK - attachment 23

      FEE64 temps OK - attachment 24

      ADC data item stats - attachments 25

      per FEE64 Rate spectra - attachments 26
       6x FEE64s < 20k. all FEE64s < 120k ( cf. 4x FEE64s < 20k, 5x FEE64s > 100k, 1x FEE64 320k earlier - attachment 12 )

      per 1.8.W spectra - 20us FSR - attachments 27-28
