Phase 1 - HCO & Commissioning

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

15 deg dipole (Scott)

• 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
• Complete macropulse chassis upgrade (replace 18 VDC + booster with 24 VDC, add protection diode to shutters), test all beam modes
• 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
  • Media:Gun2 Tee electrode 200kV HV codnitoning plan 2021 draft01.pptx

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)

• (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)
• 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)

• Bake gun, fix scheme for Kr processing beforehand
• Bake beam line
• Activate beam line NEG's
• Hi-pot any FE-er pumps
• Set voltage for all pumps
• Activate Prep NEG to overboard, bake if needed

Valves (Scott, Phil)

• 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)

• Move GN2 near gun lower, hook for air lines, caps for poly hose
• 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
• 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
