- UHV vacuum fault (series, yes?) shuts all three gate valves, test
- Gun2 valve open required for HV enable; method to jumper/bypass for HV conditioning (i.e. valve closed, but HV enable OK)
- Update drawings, document
- Air, GN2, LCW (Phil, Bubba)
- (Done)Move GN2 near gun lower, hook for air lines, caps for poly hose
- (Done)Add 2nd GN2 near girder, hook for air lines, caps for poly hose
- Fabricate, install air manifold w/ cutoff for (8) viewers, (2) valves, (2) spares
- (done) Re-install LCW manifold
- Crash inhibit (Scott, Phil)
- Install, test crash inhibit for pcup and viewer (note - fail safe test, i.e. do NOT hook up air to BOTH devices)
- Install, test crash inhibit for harp and viewer (note - does this exist, would speak to I&C early on)
- Apertures & PCup (Phil, Scott)
- Scribe new aperture stops, bag, store in tunnel, throw away ALL old stops
- Install shoulder bolt on A1, test
- Attach current monitoring w/ inline I&C protection boxes
- Reconnect LCW, I&C check flow meters clear interlock

- Install cable tray
- Decarad (Carlos, Scott)
- Tally # of heads for gun (Carlos) and beam line (Alicia)
- Mount decarad chassis, dress signal/HV cables
I&C/Software Jobs Leading to HCO & Commissioning (Apr 5 - Apr 30)
- I&C Jobs
- What to expect in tunnel?
- Similar mechanical layout => Gun + 3 girders (Y + Wien + A1/A2)
- There is now a 3D CAD model from gun to chopper, I can share pics or see Gary Hays or Shaun Gregory
- Similar utilities => LCW (A1/A2) + Air (Bubba/Phil) + Cable tray (above/below) + 3 cable drops (Y, Laser, Chopper)
* BPMs = Pete estimates 1 person x 5 days for all of the BPM hook-up and pre-beam checkout jobs

- Software Jobs
- CED
- Michele or Gary can gives us an update
- Apps
- Injector steering script getting upgrades for Wien/Solenoid controls, also needs update of correctors/bpms
- Any script that refers to CED elements from Gun to Chopper will need name review, sounds like a big job
- Screens
- I guess many screens auto-updated from CED, that's great
- Like with apps, will need name review; I guess system owners look at their own screens for oddities?
- What else for software?
