Box SWIC adapter: MSD to take delivery of prototype this week, MSD/Instrumentation will prototype to make sure it works and holds vacuum. Still on-schedule for having box SWICs available by August. Adam
Sue leading discussion with Niral and Adam to identify which BPMs are malfunctioning and how.
Cathodic protection cable break @ SSB. FESS put together PO for contractor to take a look during the summer, waiting on procurement now.
Paul Allcorn will be taking this over from me, ask Kerry to send to Paul A. as well.
HP3US/HP3DS graceful turn-off mechanism on-hold pending EE support. Sue following up with Eric Barbere. Tom will keep in touch with Chris Jensen on this as well.
Working to get C204 input for SY permit for VH94
Six-batch study pending
Adam shooting for June based on personnel availability.
Adam zeroed out trim time tables, will unmask tracking error alarms tomorrow
Mike to follow up about F17B3 and V703 beam roll
Mike created VTF17 compensation ramp and tested it. No negative effect on losses.
V703 cannot be so easily compensated for with trims. Could reduce spill time by 0.1 seconds, need to clear that w/ MI folks. Adam and Denton looking into it; may be able to modify R:V703 ramp.
P2 vacuum meetings ongoing, Sue leading
Looks promising to put all power supplies and controls at F0
Making progress. Matt Davidson to make test stand to verify CIA control of new Gamma ion pump supplies
Adam to handle beam permit input in cooperation with Vogel
Sue following up with Budlong and Neville on electrician needs
Adam to talk to Wanda about progress on new wire planes
Meson
Instrumentation
SWIC cable ringer to verify, in particular, MC6WC at low intensity (1E6): build, ready to test in the field. Mike
MT4PWC and MC6WC1 need new wires, Mike to follow up with Rich to see if he's getting those wire planes built. Adam confirmed MT4WC plane available, Rich/Wanda working to make more.
S230 suspected failing
Split optics improvement
Study to determine polarity and location ordering of Q210 and Q211
Re-tune model to move vertical waist for better split. Study to try new tune.
On-hold pending vacuum improvements
Fseps get vacuum bursts with large (200 mil) movements.
Moving above 150 mils creates bursts, IP trips more frequently
Tuned beam lower to keep Fseps below 150 mils
Shutdown plan to look at Fsep tank seals
Studies Needed
Mcenter pinhole study for Emphatic 4
Mike completed yesterday. Discovered MC5WC response is weak, shows persistent current draw at high bias voltage, same as MC6WC1. Both chambers may be old and need to be replaced.
Leaking magnets
MT4Q2, making it ramp seems to have helped the leak rate.
Viable spare found for MT4Q6. QQP002, being referenced, already been tested successfully. Moving to storage.
MT4Q6 has a known leak, but ramping it seems to have helped the leak rate.
MT5HT2 and MT5VT2 valved out due to leak (common valve between both). Breakering off for now. Des wants water lines blown out before magnet is run (ramped) without water flow.
Form Meson Vacuum working group. Mike to lead.
120V pump oil changes are less frequent now, seems to be improving vacuum overall.
Moving to reduced oil change schedule. Next week, extending run period to every 3-4 days.
208V outlet complete, new pump staged, waiting on MSD availability to switch
M05 ODH fan needs new electrical run. APS-TD cryo says ODH classification doesn't change with broken fan, AD DSO is happy with this.
MT3V 1151 card changed due to wandering setting. Now digital status (on/off) is incorrect, but magnet current is now correct.
NM
Final shielding still not in place, which is holding off ESS/Interlocks testing, search/securing
G2 supplies tested.
V420 power supply having apparent controls issue
NS1 power supplies are good, Sue documenting
NM2 SWIC replaced w/ a spool piece, leak checked successfully. To be installed, no ETA yet.
Target SWIC borrowed for MTA.
How many interaction lengths at this vacuum level in NM beamline? Carol
LCW
NS1 running, resistivity good now
NS2 cooling tower air issue
Apparent leak again, MSD investigating
Formal request in to get sprayers installed next week.
NS7 pressure/flow impacted too, improved but they need better gauges
NM3RAW up and running
Experiment will keep track of RAW resistivity
Upstairs meeting doesn't work, Sue to verify power supply is interlocked to NS2LCW resistivity and talk to Rick about meter upstairs not working.
Carol to follow up on getting NS2LCW sprayers installed.
Carol to follow up on status, may be some remaining work
NS7
Building management to improve roof
Building management to address 480V conduit water issue, has estimate from Neville (~$12k). May be able to take care with T&M before shutdown; Paul has about 3 weeks until he could feasibly start this, Sue following up.
ArCO2 gas system, MSD waiting on parts to hook up G2 gas sensor.
Carol trying to find out scope of ARR, no word from ES&H yet
Working with other departments to learn what they've done for ARRs to drive the process in lieu of ES&H guidance
NM2 supplies ready to be energized/tested, pending signatures
Waiting on NS2LCW acceptable flow/pressure
First verify water valved-in
ESS pull-keys test with Paul
Gather signatures for ramp test
There are minutes attached to this event.
Show them.
