CIS Jobs Leading to HCO & Commissioning (Jan 1 - Apr 30)

15 deg dipole (Scott)
  • (Done/SW/JG - magnet is ready for install & yes, we will use shims) Install on beam line after bake out, then align, do we use shims?
  • Current sensor for HV interlock installed and tested, ready for DC power, to set limits, fault test
  • Current sensor for FSD installed and tested, calibrated for FSD card, ready for DC power, to set limits, fault test
  • Update drawings, screens, document
Laser jobs (Shukui/Scott)
  • Complete outrigger box, install, test with laser room shutter, update LSOP
  • Flush chiller, decide on PM schedule, fill
  • Re-install/align Pockels cell
  • Re-install Hall B amp in permanent location

  • Update drawings, document
Gun HVPS jobs (Carlos/Bubba/Scott)
  • Prep for HV & conditioning (SF6, tank, DILO, cables), check HV interlock made up, HVPS setpoints/controls ready
  • Regrease ceramic after bake
  • Make sure back-up electrode is available
  • Remove old HV parts (150kV glassman, old HV interlock chassis, VME interface card), once we can make HV again ... temp replace with Ortec bias PS (if needed)
  • Pull additional Anode bias HV cable near Glassman rack, I think that's where we ultimately want to bias PS star ground to HVPS, also to patch to QE scan ammeter
  • Develop HV commissioning plan/staffing
Wien HVPS (Carlos, Scott, Riad)
  • (Done) Add placards to ISB racks
  • Install HV Switcher chassis at ISB, complete cabling between rack components
  • Drop/pull HV cables from HV switcher outputs to Wiens
  • Wien EDM and InjSteer screens updates with HVPS and new PS epics values, tested, ready
  • Update screens, drawings, document
Ion Pump Power Supplies (Scott, Marcy, EES)
  • (Done) Finalize IP names for songsheet media:210209_ion pump names.xlsx
  • Complete mapping between all IP and power supplies (gun to choppers)
  • Complete UHV power supply upgrade, remove temp PS, spare PS on shelf (identify cabinet area for spares): This is Jim Kortze & co., not planned for this down?
  • Work with software to reprogram UHV PS EPICS names, can we have unique identifier from old names?
  • Re-install (2) HV patch boxes, update box labels, pull HV drop cables to patch boxes, updated labels
  • Update screens, drawings, document
Vacuum (Marcy, Phil)
  • (Done)Bake gun, fix scheme for Kr processing beforehand
  • Bake aperture girder beam line, activate NEGs
  • Bake wien and y chamber girders, activate NEGs
    • Make cables to activate Y chamber NEG pumps during bakeout (draw up and send to Fab)
  • Activate beam line NEGs for DP stations downstream of chopper
  • Hi-pot any FE-er pumps
  • Set voltage for all pumps
  • Activate Prep NEG to overboard (done), bake if needed (Joe: see if cathode activates in prep chamber? No water in RGA scan)
Valves (Scott, Phil)
  • (Done)Work with I&C and software, controls for (3) valves (note - confirm valve type different)
  • Build, install, test (3) shut-override boxes for valves
  • 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
Electrician jobs (Scott)
  • Relocate floor outlets (done)
  • Bond girders (Shaun has holes drilled on girders already for this)
  • 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

    • 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
