I was called by Security at 8:05 PM for an ODH alarm in the South Linac. My investigation revealed that the Analog Input module was passivated, affecting four ODH channels in the South Linac (OM21, OM22, OM23, and OM24). I resolved the issue by unplugging and replugging the AI module, restoring ODH coverage to the affected area. No obvious cause for the passivation was identified. I will continue to investigate offline to determine the root cause.

The UHV ion pump supplies are communicating through epics, but don't seem to be responding to what should cause vacuum activity. Changing the setpoint (fig 1) and opening/closing VBV2I01 (Fig 2) don't show any response.

Bypassed 45 minute timer for injector gun valve - the valve shuts after 45 minutes if the high voltage is not on, but we need it open for the laser alignment work.

This will be restored after gun alignment is complete.
