Electrical

  • Electrode PCB - designs from Crispin:
Line: 45 to 46
 
    • DIN 41612 Type C 96 pin connectors. Six sets of two anode-cathode pairs separated by grounds, with a,b & c lines ganged. Two connectors per side with strips read out on both sides. Need to check polarity of these connections.
    • The anode PCB has blocking capacitors on the left hand side to isolate the DC offset of one NINO card.
    • There are 10MOhm resistors to pull the strips down to ground - this prevents HV building up and killing the NINO cards.
Changed:
<

>
>
    • Make sure the HV lines are on opposing ends of the PCB.
    • Check anode-cathode board interconnects - v1 PCB is sized for through hole wires, not Jumper pins.
    • Is VHDVI the same as VHDCI? - seems so, the cables are used for TimePix interconnects, also.
    • Boards made by CERN fabrication service.
    • PCB layout in the OHWR.

    • DIN 41612 Type C 96 pin connectors. Six sets of two anode-cathode pairs separated by grounds, with a,b & c lines ganged. Two connectors per side with strips read out on both sides. Need to check polarity of these connections.
    • The anode PCB has blocking capacitors on the left hand side to isolate the DC offset of one NINO card.
    • There are 10MOhm resistors to pull the strips down to ground - this prevents HV building up and killing the NINO cards.
    • Make sure the HV lines are on opposing ends of the PCB
 
    • Is VHDVI the same as VHDCI?
