HV Biasing

The original plan was to follow the wire bond diagram for module construction. After talking with Craig it became clear that we should vary the plan some. To correctly connect the HV we had to do the following steps:

Changed:
<
<
  • Solder a wire on the connector pins to short HVret and LV GND '
>
>
  • Solder a wire on the test frame to short HVret and LV GND
 
  • Connect the four corners with AC connections, then connect one of the inner corners of the hybrid to the bias ring to route the leakage current into the HCC
  • Not connect the HVret on the hybrid to the frame, as R2 creates a lot of noise for the system.

Power Board

Rhonda glued the power board by hand with 24hr Epolite 5313A epoxy and fishing wire. When the power board was first placed, there wasn't enough glue. It was then picked up by the shield box, and glue was added to the bottom of the power board. To hold it in place, a foam and plexiglass piece was improvised, and a weight was put on top of it. In hindsight, we should have used the usual brass weight instead of the one pictured. When gluing the power board, we had to be careful not to get glue on the guard ring, as that is known to cause early break down of the sensor.
