Vacuum is holding in 1L05, 6, and 7. RF has given 1L10 back over to us unfortunately with cavity 3 bypassed. Now we are trying to bring back a cavity to make up for that loss.

Once that is done, we will start tuning beam around the machine. We do not expect good orbit recovery as the machine has been down for a long time and multiple components have dropped and come back while we were working on 1L06. That being said, we believe machine tuning could take some time.

Looking through the archiver, steering at 0I01B (directly upstream of A2) has an inverted effect in both planes at 0I05, and there is relatively litrtle coupling between the planes. This looks to point to the discharges (where beam snaps towards the charged object), which move the beam down and beam left at 0I05, is the beam moving up and beam right near the suspect area. Looking at the songsheet, it does seem like the harp is beam right and up.

In addition, we will also test the BCM fibers from BSY to the Injector Service Building.
All in the attempt to troubleshoot and eliminate nuisance BCM LIU trips.

We see a very slight shift on the MS, but not on A1 or A2 (visibly at least). The charge time of ~30 minutes is unchanged. IPM0I01B does not see it. This confirms it's most likely either at or after A2 and before the chopper.

Things are looking good at VIP1L06A, VIP1L07A, and VIP1L07B. We feel comfortable opening VBV1L05B

Seeing a slow increase in VIP1L07A. VIP1L06A looks good. Now we are going to open VBV1L07A to see how VIP1L07B is affected. We'll continue to watch this for the next half hour or so.
