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

    • 10 total - all unrotated
    • 3 new style => NEG coated large bore (2.5" ID); mapped by Musson (Kx/Ky values available)
    • 7 old style => 5.5" long end tapped
  • Viewers
    • 8 total - all chromox except ITV0I02 (YAG)
    • Crash inhibit #1 : ITV0I01 and Polarized Cup IFY0I01
    • Crash inhibit #2 : ITV0I02 and Harp IHA0I02
  • Harps
    • 1 total - IHA0I02 (YAG), on same cross as viewer ITV0I02 (requires crash inhibit)
  • Wien HV
    • Tony status update

* Current Monitoring - Pete estimates 1 person x 3 days for ItoV, Picoammeters, Gun FSD LCW waterflow interlocks)

    • 3 total - same as before (PCUP, A1, A2)
    • PCUP identical as before, just a new location
    • A1 current monitoring as before, linear bellow motion now has STAC5 motor (so remote or manual; has 3 stop positions
    • A2 current monitoring as before, linear bellows manual as before; has 3 stop positions. Used by PSS group for kicker
  • Valves
    • 3 total - all have in-line EPICS shut over ride capability (CIS installs this box)
    • Gun valve - VBV2I01A (new name), otherwise same all metal gate valve
    • Beam line valve - VBV1I07 (same name), same all metal gate valve
    • Beam line valve - VBV0I02 (same name), but now all metal gate valve, requires cable terminations like VBV1I07
    • All 3 valves tied to UHV vacuum fault (100 uA limit)
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?

Magnet/DC-Power/Software Jobs Leading to HCO & Commissioning (Apr 5 - Apr 30)

DC/Magnet Jobs
Software Jobs
  • CED
  • Apps
  • Screens
  • What else for software?
Other magnet jobs
  • (JM) Complete magnet table I circulated
  • (JM/LL) Initial QW measurement and assessment (sufficient for CED), summarized for Gary
  • (RS/GC) FG solenoid special hysteresis for Gary
  • (RS/MJ) Magnet info for Inj Steer spin calculations
  • (JM/JG) Decision on spare DR fabrication and alignment
  • (LL/JK/JM) PSS kicker - does MMF have any responsibility here, maybe just PSS?
  • (LL/JM) Second QW measurement, what's the scope here?
  • (JM) When is the rotating coil stand ready?
  • (JM/LL) Reconciling MHD discrepancy
  • (LL) Report on QW
  • (LL) Report on HD
  • (LL) Report on PSS kicker
