When Hall C requested 17uA, we started to trip ILM2T09. Did some slight steering in 4S and 4T, and adjusted Gp in the North and South. After that we had much more stable beam.

xC went down for about 20 minutes for a target change. When we came back the 1A was very shmeared and the lock zone energy increased by 0.283 MeV. Had to adjust the NL GP by +2.4 degrees to get it back on crest.

Does not appear to be related to AHU01.

Water filter was recently changed. Guards say that cryo on call is coming in to take care of the current alarm on CHL turbine 1 (south linac)

Difference between past alarms and now is that CDP16270 (I assume a pressure PV near the water filter) usually rises, drops, then triggers an alarm. However, this time CDP16270 was rising, triggered an alarm, and has yet to drop.

FIG.4
Ultimately, Linac supply seems fine. However there is some small disturbance to Linac CHL supply pressure and perhaps the 2K Mass Flow in the North Linac. Possibly/probably unrelated
