Rad fencing in F-sector due to construction Adam
VH94 SMPS upgrade: Commissioning soon. Adam
Startup checklist Adam
Meson
MS2LCW pumps
Pump #1 trips on over-current on startup Mike
Pump #3 needs new motor, waiting on parts
MSD to size pump and procure hose. Parts arrived. Adam
Upstream M02 leak not repairable without draining system. MSD to tighten valve stem to see if it helps.
MS2LCW head pressure, tank levels. Appears that gas bottle for head pressure is empty, could be cause of level rise. Gordon
MS3 vacuum PLC progress: Mike
Paul A. and Mike to look into installing CT clamps on vacuum pump cables.
Mike getting drawing from Dan, then CTs from Paul K., then installing.
MC6D-2
When MS2LCW is back on, leak check MC6D-2 and look for any regulators or restrictors
MC6D-4
Check leak once MS2LCW system is back on.
F1 single-point LOTO: work finished. Ops working on config control paperwork approval from ES&H. Paul
Need to remove dehumidifiers (F2 and F3) once MS2LCW up and running. Paul
M01 rad fence needs straightened out, solution with FESS confirmed to not count as excavation (concrete supports). Job finished, waiting on confirmation from ES&H. Tom
Startup checklist Mike
SWIC cable ringer to verify, in particular, MC6WC at low intensity (1E6), check cables. Specs from McArthur, ordering parts. Mike
Can SWICs run in Proportional mode (higher voltage, PWCs?), does polarity matter? From Dan: can go as high as 2200V, no change to polarity. Adam check MCenter Droeges can go this high.
Double-check Tom’s optics for MCenter 120 GeV mode Adam and Mike
NM
Vacuum
All pumps hooked up, downstream pump needs turned on.
NM2 multiwire leaking, Carol following up w/ MSD.
How many interaction lengths at this vacuum level in NM beamline? Carol
NS2LCW, backup pump (pump #2) pending
NS1LCW system status? Des agrees to have Dan jog the system. Adam
Magnet labels/signs; Enclosure C finished, taking longer than anticipated. Adam and Mike
Some rack labels needed Adam
G2 single-point LOTO electrical work finished. Working with Ops on config control paperwork; waiting on ES&H to approve forms. Paul
NS2LCW sprayers developed a leak, Adam and Kevin about timeline for colder water, help MSD manage manpower.
