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

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

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

(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

(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

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

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

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)
