Voltage divider
- Voltage divider schematics
- The 5-pin connector on the voltage divider is Samtec Part # IPL1-105-01-L-S-RA-K (male):
- Pictures of the assembly:
Custom cable from voltage divider to PCB boards
The cable has a female SAMTEC 5-pin connector IPD1-05-S-K on one side, with 4 crimp contacts CC79L-2630-01-L. On the other side the cable has a SMA RS PRO 546-3210 connector (Datasheet, Crimp instructions) and Fischer connector S 102 A 018. Both the HV and the anode cables are KX3A type and 3-mm external diameter. 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.
- Each HV cable is plugges into a Fischer D 102 A018 connector on the PCB board
- The anode cable is plugged into a SMA CINCH CONNECTIVITY 142-0701-501
- The anode signal gets out at the opposite side of the board throught an identical connector SMA CINCH CONNECTIVITY 142-0701-501
- The HV enters through 2 connecteurs SAMTEC PMSD-15-206-K-D-LUS and 1 PMSD-08-206-K-D-LUS connectors
- The LED sitting in front of each PMT are controlled by a ribbon cable plugged at the bottom of the board to male 2x36-pin SAMTEC connector TST-136-01-L-D
- Board schematics: Layout.pdf, Connections.pdf, Parts.xlsx
HV ribbon cables
The PCB and the HV panel are connected by 20 AWG cables. Three cables per detector column: 2 cables have SAMTEC PMSD-15-206-K-15.40-D-LUS connectors and 1 cable has PMSD-08-206-K-15.40-D-LUS connectors
Notice that 20 AWG = 7.2 A, and our currents are of the order of micro-Amps.
LED control cables
Ribbon cables with SAMTEC connectors HCSD-36-01-N on each side:
Anode signal cables
- Signal come out at the back of the PCB boards.
- There are KX3 cables with a SMA connector RS PRO 546-3210 on one side and a panel-mount LEMO PES.00.250.NTME31.
- The length of each cable depends on the row of the detector (longer cables for channels at the bottom).
- The LEMO connectors are mounted at the top of the NPS box (see LEMO panel below)
- Cable schematics
Patch panels at the top of the NPS box
There are 3 panels of the top of the NPS box:
Signal panel (LEMO)
HV panel
The HV panel has 2 SAMTEC connectors PMSD-15-206-K-D-LUS and 1 SAMTEC connector PMSD-08-206-K-D-LUS per detector column (a total of 30 columns).
The board is made of two 15-pin SAMTEC IPBT-115-H1-T-D-K and one 8-pin SAMTEC IPBT-108-H1-T-D-K for each detector column (associated with one PCB board)

- Input connectors
LED panel
Made of SAMTEC connectors HCSD-36-D-86.60-01-N-G (one per detector column, i.e. a total of 30)
