Monday, April 15, 2024, 14:33: On Friday it was noted that the EE was being troublesome. If we put -500 V on the EE the PS would deliver -1000 V. However it would slowly trickle downward. elog:1002.

Tom H. had a look at it this afternoon & determined the PS is operating, however the signal going to it is peculiar. Controls group as been notified as well. Awaiting further response.
