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)
- Ion pumps
- Marcy's final list media:210209_ion pump names.xlsx
- 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
- Spreadsheet updated after further feedback media:210301_Phase1_Magnet_Summary_v3.xlsx
- Spreadsheet updated at 3/1 SAD planning meeting media:210301_Phase1_Magnet_Summary_v2.xlsx
- Spreadsheet initially media:210301_Phase1_Magnet_Summary.xlsx
- Software Jobs
- CED
- Apps
- Screens
- What else for software?
- Other magnet jobs

- (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
