Electrical Connections
CAUTION: Do not use a wrench to tighten the SMC
connectors on the bias and electrometer cables.
Connections should be finger tight only.
1. Referring to Figure 6 as necessary, connect the bias and electrometer
cables as follows: the BIAS-B cable to the top electrode (closest to the
discharge electrodes), the electrometer cable ( ELECT) to the middle,
and the BIAS-A cable to the bottom electrode. This setup is the same
for both detector models.
2. Connect the high-voltage cable from the detector to the pulse supply, and
connect the pulse supply cable between the back of the controller and
the pulse supply. Connect the heater cable from the detector to the back
of the controller.
