• 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?
