First Electrical Module (ABC130)

  After flipping the wire bonds we were able to run all of the tests and get results.

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:

  • Solder a wire on the connector pins 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.
