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
