At 8:40 am VTP0L04 started reading a high pressure alarm. This seems to be an after effect of an earlier event. At about 6:50 am the RF On/Off tool was used to turn off RF in the Injector and North Linac, after which pressure spiked. After vacuum stabilized it seems to have settled just at the setpoint for the turbo pump to turn on, causing it to turn on repeatedly. This was noticed and the pump was set to local mode and the pressure continued climbing very slowly for the next 1.5 hours until the event at 8:40.

Retracted A1. PB can stay on, the comparison should still work.
VWien off for now, MFX2I01 = 208, MFX1I03 = 196.
MFX0I01 = 0.
HWien is still limited to 60 degrees pending DRVH adjustment, so "on" means 60 degrees today.

Measuring beam size on 0I02 viewer for HWien on/off as a function of MFG1I04 setpoints under the constraint that B = -A, avoiding coupling for now.

Spoke with Greg Marble.

Greg, with additional SRFVAC support, will begin Monday morning swapping five ion pumps: VIP2C00A, VIPAT09, and VIP3C{01,03,03A}. VIP3C04 is elevated but still in the "green" range. Swapping the upstream pumps will bring it down even further. VIPAT09 is railed even after the earlier nT-VIP swaps, and with its closeness to the others makes good sense to address together with the 2C and 3C ones.

Anticipates this job taking 2-3 days. This works fine, even if it spills over another day or two.
