Overview

Voltage divider

Voltage divider schematics
The 5-pin connector on the voltage divider is Samtec Part # IPL1-105-01-L-S-RA-K (male):

Custom cable from voltage divider to PCB boards

This cable carries the HV to the PMT divder and reads the anode signal. 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] (signal) and a Fischer connector S 102 A 018 (HV). Both the HV and the anode cables are KX3A type with 3-mm external diameter. The cable length is 375 mm.

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 plugged 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 through an identical connector SMA CINCH CONNECTIVITY 142-0701-501
The HV enters through 2 SAMTEC PMSD-15-206-K-D-LUS and 1 PMSD-08-206-K-D-LUS connectors at the top of the board
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

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

Cable schematics

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:

Cable schematics

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)

This is not patch panel per se, but a simple panel with holes where the LEMOSof the anode cables are mounted on.

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 2x36-pin SAMTEC connectors TST-136-01-L-D (one per detector column, i.e. a total of 30)
