Halls A and C Spectrometer Support Group Whiteboard
Contents
Priority Items
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 - ordered - need to remove old compressor and dryer.
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.
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
