AIDA DSSSDs and FEE64-DSSSD cabling are electrically isolated (by design) from snout, mounting rods and support assembly.
FEE64-DSSSD ribbon cables screened by 3M 1245 Cu foil, drain wire to FEE64 adaptor PCB
AIDA FEE64s are electrically isolated (by design) from the AIDA support frame and each other.
BNC PB-5 test signal
daisy chained to FEE64 adaptor PCBs via screened RG174 cable/Lemo 00-250
CAEN N1419ET DSSSD bias
daisy chained to 1x p+n junction FEE64 adaptor PCB/Si wafer via screened RG174 cable/Lemo 00-250
CAEN N1419ET outputs floating, locally grounded by 1x n+n Ohmic FEE64 adaptor PCB link/DSSSD
AIDA FEE64s are connected to the DESPEC 19" rack
power (AIDA FEE64 PSUs),
timestamp (AIDA NIM MACB modules),
system console (via serial-USB cables to USB hubs),
RJ45 network cables (24 port Gbit network switch)
AIDA PSU PowerStax MS1U-6C-222233-01 - see attachments 1-2
PSU outputs V+/V- and common
no direct ground connection
AIDA MACB
HDMI cabling MACB-FEE64 is screened and shield is grounded
system console
?
RJ45 network cables are coupled by ferrite beads to FEE64 PCB and network switch
