Switchyard/Meson/NM meeting

US/Central

SY

  • F3 fencing
    • JULIE entered for July 11, FESS in the loop. Sue
  • Instrumentation
    • 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 created BPM status spreadsheet, scheduling meeting with Adam/Niral to discuss.
  • 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.
  • 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
    • Met with Jim Morgan to discuss. F17B3 can be compensated for directly with I:VTF17. Mike to create ramp and test.
    • 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 to test this with Sue.
  • F3 LCW pump pressure sensor died, addressing on 24th (down day)
    • Didn't get addressed, Sue following up
  • 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

 

 

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.
  • 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 planning
  • 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.
  • MC6CV readback noisy, Adam to swap position readback card on Thursday.
  • Form Meson Vacuum working group. Mike to lead, Adam to assist.
    • 120V pump oil changes are less frequent now, seems to be improving vacuum overall.
    • F1 208V three-phase outlet under-rated, working on it. Want to get 208V pump in F1 that can pump water. FESS working on 208V outlet today.
  • 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.
  • MC1D power supply repaired, Mike to re-scan power supply since the transductor was changed

 

NM

  • Final shielding still not in place, which is holding off ESS/Interlocks testing, search/securing
  • G2 supplies tested.
    • V420 power supply needs replacing/repairing, tripped breaker
    • V424 (PEI), VT420 (Krafczyk switcher) regulation issues
  • NM2 SWIC replaced w/ a spool piece, leak checked successfully. To be installed, no ETA yet.
  • How many interaction lengths at this vacuum level in NM beamline? Carol
  • LCW
    • NS1 running, resistivity good now
    • NS2 cooling tower air issue
      • Back up and running.
      • New regulator for cryo platform arriving today, should fix flow issue.
      • Formal request in to get sprayers installed next week.
      • NS7 pressure/flow impacted too, hopefully cleared up this week.
      • Tower 1 being fixed Tuesday
      • Tower 3B has bad mounting fixture
    • 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
  • 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.
