Voltage divider
- Voltage divider schematics
- The connector on the voltage divider is Samtec Part # IPL1-105-01-L-S-RA-K:
- Pictures of the assembly:
Custom cable from voltage divider to PCB boards
The cable has a SAMTEC connector IPD1-05-S-K on one side. On the other side the cable has a SMA RS PRO 546-3210 connector (Datasheet, Crimp instructions) and Fischer connector S 102 A 018. The cable length is 375 mm.
- Cable schematics
- Picture of the cable:
PCB boards (one per detector column)
The HV and the anode signals of each column of the detector is routed through a PCB board. This boards also holds one LED per channel.
- The HV is distributed from the top of the board through 3 ribbon cables.
- The LED sitting in front of each PMT are controlled by a ribbon cable connecting at the bottom of the board
- Anode signal from each channel get out of the board through the opposite side and through SMA connectors
- Board schematics: 1, 2

LED control cables
Anode signal cables
Patch panels at the top of the NPS box
There are 3 panels of the top of the NPS box:
