COMMENT ON Modify 0L02 RF drive system for booster upgrade
Larry Farrish "This morning replaced all waveguide air supply hoses in the new zones NL21-26, except the main supply at the top of the ceiling I will get a taller ladder for that next week.
Waveguide in the Injector has been taken down, I will continue to disconnect cabling from module next week."

status phase2 injector work Day 4
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 Install and HV process 200 kV electron gun
Particle counter shows 50-100 inside the clean hood.
Krypton evacuated between the bottle regulator and leak valve at the gun. I left the Kr line under vacuum for now.
After evacuating Kr line, connected pump cart to right angle valve upstream of gun overboard IP. Right angle valve remains closed of course. Started pumping on the line at ~ 11 am.
All of these tasks are in preparation for venting and removing HV chamber on Monday 03/27/23.

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.
