Gun has been up to air for 3 times. It could be oxidation, contamination. Or it could be gun died, less likely. Roasting the gun to burn off the contamination is an idea. Chad just roasted gun for with higher current, we saw gun current increased many times. We will leave roasted for one night.

Calibration
Camera Triggering
Triggering
We sent the pulse from gun trigger to a pulser. We delayed the pulse 8 micro-second, created 8 micro-second wide pulse with 4 V amplitude. This pulse triggered the camera. In following figure camera trigger pulse and signal 45 degree Faraday cup is shown.
Camera Configuration
Camera operated stably in pulsed mode. Run script saved and given
