Saw that the Turbo for 1L25 was start/stopping this morning. Called MCC to turn the turbo off. Looking at the archiver shows that at around 3:51 AM the insulating vacuum saw a spike in pressure tripping the interlock for the turbo. The pressure couldn't recover enough for the turbo to remain on. VAC group will need access to close the gate valve to cryomodule and try to restart the turbo. Might have to replace the scroll as well.

Downloaded my AllSave from 2/13 with all Inj magnets, warm RF, and BPM rels. Removed Master Slit and Central Plug from Chopper.

Fig.1: Set H.&V. Wien to -25
Fig.2: Chopper/Buncher/PreBuncher phases
Fig.3: Restored corrector BDLs
Fig.4: As found orbit to FC1. Seems things have shifted a bit. Especially around the H. Wien. Not sure what that is about.

Re-flattening orbits for now.

Fig.5: Flattened orbit to FCup1
Fig.6-11: Beam to 1D.

Taking an AllSave here then continuing on.
