Priority Items

Install VVU on SBB power supply - VVU is by the supply (Joe)

Readout for LCW pressure sensors added at end of beamline walkway (not started)

Check if optocoupler is missing in LQ2 FuG - Looked for this. Didn't see one on the main boards, but realized as I am writing this, maybe it was for the interface for remote polarity switching? --Ellen

Buy and replace MFCs in old FPP mixing system - MFCs on order

Replace air compressor in Hall A Gas Shed - asked for quote

Gas manifolds for GEM gas cylinders (started)

Hall C Moller: setup new chiller, modify bertha, get new helium lines installed when they come in and test magnet cooldown

Nitrogen supply for GEM gas cylinder valves (Clippard valves and cylinder controller) (not started)

Gas mix controller and MFCs for GEM detectors (not started)

Determine 100% liquid level set point/Hall C magnets.

Warm up HB.

Add "T's" and pump out ports to HMS magnet vacuum gauge ports.

Add ventilation to SHMS Dipole flow meter shielding.

Find 4 atmos leak in Hall C.

Move ozone meters from VME to PI.

Add fan to beamline side lead (HB)

Modify HMS lead heaters, add perforated sheets up stream and add a perforated box downstream to fit heater.

Move equipment back to UPS power

Would Be Good To Do Items

Remove actuators from right arm magnets. (Dipole/Q3 complete)

clean up R-arm supply platform

clean up L-arm supply platform

HMS/SHMS Heater and fan changes, fixes, upgrades etc.

Calibrate and op-check spare warm return valves for Hall C.

Add bypass switch for SHMS UPS - Switch ordered

Do We Still Need To Do These?

Possible Future Items

Remote reset for Hall C spectrometer motion (maybe next year)

Install new liquid level meters on SHMS- Install done, waiting on software and LN2 probe cal to go live (need Steven).

Fix LCW leak in LD1 Dynapower

Replace pressure sensors on the Hall A Ethane manifold

Replace ground fault module in LQ1 power supply

Test LQ2 FuG with new polarity reversal switch.

Swap out MFCs in VDC mixing system
