SY
Timing cable replacement: Installation of replacement cables and conduit underway. Construction to be complete by Sept. 15 17. Adam
Rad fencing in F-sector due to construction Adam
VH94 SMPS upgrade: Electricians finished 480V disconnect. Adam
Possible leaks on Remnant LCW system (F-sector most likely). LCW system to be turned on early next week, then we’ll see. Adam
Asked MSD to turn on ArCO2 gas systems (TG-8, MS3, and G2) Adam
Startup checklist Adam
Meson
MS2LCW pumps
Two pumps down, only one available Paul
Pump #3 has bad motor, waiting on parts
Pump #2 has bad starter, waiting on parts. Worst-case, can use starter from pump #3 if necessary.
Given FESS until Sept. 20 for acquiring parts, then backup plan for starter
M02 header leak repair
MSD to size pump and procure hose. Meeting tomorrow afternoon with MSD to discuss plan.
Alarmable (ACNET) high-level float: Circuit box complete and tested. This week, running cable, testing M02 patch panel. 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.
MC6TGT as-found schedule. Gordon
Starting up with target in place.
Asked ES&H to re-install grate, target box. Then replacing back-scatter scintillator. Gordon
MC6D-2
Magnet in place
Power cables and klixons connected
Remaining: MSD working on turning on vacuum pumps, connecting LCW
MC6D-4
Check leak once MS2LCW system is back on.
F1 single-point LOTO: work finished. Ops working on config control paperwork. 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) Tom
Startup checklist Mike
SWIC cable ringer to verify, in particular, MC6WC at low intensity (1E6), check cables. Specs from McArthur, gathering resistor. 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
Carol The pump seal is the issue
How does the NS2LCW piping run? Is it buried? Making progress. Carol
Tom concerned about whether NS2-NS7 piping is exposed. May not need glycol? Carol following up to look in the field.
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. Cleaned up old disconnected. Paul
Latest time for safety system tests to be complete to start power supply tests? February 2022 is SpinQuest estimate for beam. Adam, waiting to hear back from Jensen about PS commissioning time needed.
NS2LCW sprayers developed a leak, Rick to get back to Adam and Kevin about timeline for colder water, help MSD manage manpower.
