Priority Items
Install VVU on SBB power supply - VVU is by the supply
Install spring washers on SBB and BB busbars and connections
Readout for LCW pressure sensors added at end of beamline walkway (not started)
Fix LCW leak in LD1 Dynapower
Replace pressure sensors on the Hall A Ethane manifold - PR for sensors to be submitted in January

Buy and replace MFCs in old FPP mixing system - MFCs on order
Replace ground fault module in LQ1 power supply - on 2nd floor of CH
Replace air compressor in Hall A Gas Shed
Find video cables from hall in the CH
Gas manifolds for GEM gas cylinders (started)
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.
Build better "shield hut" for SHMS lead flow controllers.
Warm up HB.
Add "T's" and pump out ports to HMS magnet vacuum gage 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.
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.
Hall C Moller: setup new chiller, repair compressor, modify bertha
Add bypass switch for SHMS UPS?
Do We Still Need To Do These?
Test LQ2 FuG with new polarity reversal switch.
Mount Left Shield House temperature readout in CH
Find and connect NMR cables in CH
Swap out MFCs in VDC mixing system
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).
