Updated iCal, was using the 2025 high energy for Dummy, which had lower values.
Not tripping ICs anymore

Ion pump suddenly started failing, maxing out over the course of under an hour and being seen in the differential pump station, but not bad enough to close any valves or show up downstream. Since the event did not appear to be related to beam loss or sudden increase in field emission (the jump in the 6R10 IDX was from coincidental gang phase adjustment), it is likely the pump itself failing. See the linked log.

Called about VIP2L01 Vacuum spike that caused adjacent pumps to spike as well. The ion pak for this supply was changed out about a month ago and it was noticed that the pump might be needed to be replaced this next SAM. Spike in vacuum could be result of pump dieing and releasing particulates through beamline to adjacent pumps causing the spikes seen. Since spikes didn't reach high enough at DP station to cause valves to close we will let it be for now. If spikes cause valves to close we can disable the power supply by removing fuse from upstairs.

Hall C SHMS HB Interlock Fault

Summary:
While setting up to adjust the SHMS, hall staff were stopped by an SHMS HB fault they could not clear. They contacted their SME, who is on the way to investigate.

When pausing beam to check orbits and path length, we noticed that inserting the Hall C dumplette did not trip FSD. Checking the tree, it was found that with the destination masked to Halls B and D, the gold mask for the Hall C dumplette was set to masked. Checking back through previous destination masking, this seems to be occurring whenever Hall C is not included in the masking, but it's not immediately obvious to me when this started occurring because the masking PV is a combination of every state on the node. Figures 1-3 show masking state at the time the issue was noticed and anomalies.

VIP2L01 readback has stayed high. We are in contact with I&C on-call. They are investigating and will call us back shortly.
