In no particular order

1) CAEN 83xx series NIM bin (Ortec 533A output noise issue)

   observe +/- 6V, 12V, 24V lines with/without load 

   try new CAEN NIM bin and/or NIM bin of different type

2) Measure actual voltages at FEE64 power connector input

   OH suggests fab of power adaptor for safe observation - contact EW

3) rev B adaptor PCB

   invert 125 way ERNI - check for mech conflicts
   paired HV input (avoid Lemo-00 T pieces)
   consider isolating test/HV Lemo-00 shells from PCB ground (loop elimination)
   straight jumpers
   shrouded Samtec headers - consider mech issues/consequences of using eject clips too
   re-visit HV filtering & separate trace ground

4) isolation transformer

   as practical matter may be necessary to operate all platform from isolation transformer
   consider hire of appropriate unit

   need method to measure isolation - will require permit to work or equiv

5) investigate S4 area ac mains

   NH discussing with GSI electricians

6) Systematic measurement of AIDA PSU noise

   Spec linear AIDA FEE64 PSU

7) Redesign of snout
   Return to 1mm welded box Al for lower stage of snout  for added rigidity

8) Revisit calculation of cable lengths. Particularly for the triple
