finished disconnecting all water lines from phase2 beamline, plugged the supply and return lines at the manifold, water back on, no leaks
Disconnected the water to buncher (ball valves inside the tunnel, along cable tray above chopper). Now there’s a leak at one of the supply lines at chopper2 cavity. Small leak, I turned OFF water flow.
All magnets and I&C stuff now disconnected
Larry removed most of the waveguide, thanks
Prepped the removal of the spectrometer beamline for tomorrow

COMMENT ON BO dipole magnet mapping - SAD 2023

Log Number: 4153283Logbook(s): Body: 

Magnet Measurement:

We teamed up on the MBO dipole and have removed it from Injector beamline and carefully removed the hall chips.

Matt has some fit checks to do at UITF. If you need 1006 magnet steel for new return legs, just let us know.

If not, we will see it when you drop off @MMF for QA and Magnetic Measurements.

COMMENT ON Plasma processing in CEBAF accelerator

Log Number: 4153271Logbook(s): Body: 

Once the OSP is signed by the stakeholders, it would be helpful to attach one to this ATLis as the link will get buried in the comments section as updates come in. Also, a printed copy at the processing site wouldn't hurt either.
