AD Weekly Friday - 2018 Scheduling Meeting/Weekly Summary (23 Mar 2018)
Crew Chief
See slide.
Operations Coordinator
Running at design rate, timeline full.
Linac
See slides. Maintenance period on Tuesday ~ 6 hrs. EESupp upgraded Marx Modulator cells. Patch redone on LRF5 LCW. Emittance scans Tuesday evening. Beam to NIF on Weds for most of the morning. LRF4 filament hose this morning, fixed just before 9:00, right now running OK after recovery
Booster
See slides. Good week, eff. remains ~94%, Came up slightly lower after downtime but they are running more beam (muon), Ops have been doing a good job balancing intensities/losses on TLMs/demands, SY has been running, supplying ~5E11 as req., shutdown was good, did both tunnel and upstairs work, patched some leaks in L2 area (vacuum improvement), did studies (BRF phasing @ inj), tuning for better efficiency to keep up with intensities and rep rate, downtime 30 mins (BRF trips, BRF5 util yard breaker), good going into weekend.
Main Injector & Recycler
See slides. (pics of MI52 region) Went to full intensity NuMI within 4 hours of turnon. Major downtime was MI52 kicker replacement. Had small vacuum burst during startup. New ion pumps installed on the MI52 septa, also inspected LAM40 leak, did rad studies around ring (DALE & barcode), MI-8 IP cableing repair (got 3/4 back on), studies requested next week—1 hr dedicated time (no NuMI) for measuring sextupole centers and collimator studies, 4 hours at 1.4 rep rate.Dedicated study needs BNB operation, targeting for Tuesday. Will finalize at Monday's 9:00.
NuMI
Valved out flow on Horn 1 hanger, leak went away. Borescoped cross-drain and that was clean. Rebooted orbit verifier with new code.
NuMI Experiments
As reported on Weds, both MINERvA and NOvA used the downtime to perform work: MINERvA swapped out some boards; NOvA also did (in their FD), they topped off their detector LCW reservoir, and did some expert training, running well.
Booster Neutrino
Took advantage of downtime during day to get head start on summer shutdown jobs, slightly higher rad in MI-8 as expected now with muon running design intensity. (LOTO training today 10:30 - Chris J.)
BNB Experiments
Used downtime to improve external trigger rate (doubled), water leak in sump discharge fixed. Thanks goes to FESS & company.
Muon Rings
Very good performance on beam, some of best. During shutdown fixed vertical target motor. found vacuum leak and fixed. Yesterday g-2 requested full rep rate (11.4 hz), successful to this point longest ever, essentially doubled rate. A few growing pains (airborne Rad mons get right limits, some losses in beamline, AP0 dump, doing some tuning/studies getting ready for weekend. Plan to run this mode over the weekend.
Muon Experiments
Running smooth, some of the pulses are “bouncing around”—jitter? want to revisit kicker timing and check RF stability.
SY120, Neutrino Muon, Meson Test, Meson Center
Another water leak discovered @ H201-12 in Encl C, but were not able to fix it in place (only patched), keeping an eye on remnant LCW level and have a viable spare ready to replace during summer shutdown. Option 'B', could valve out and run without cooling if necessary if patch fails.
SY120 Experiments
Running smoothly. Pleased with quick startup from shutdown. Switching to new experiment next Wednesday.
FAST/IOTA
All ion pump cables have been terminated. Termination of the Dubna quads will start next week. BPM terminations are nearly complete at the electrical service building. IOTA LCW manifold testing continues. Power supplies for the RadiaBeam quads should arrive next week. Controls installation for the ring power supplies should begin next week. Installation of the RF cavity beamtube should be completed within 2 weeks. Assembly and leak checking of IOTA vacuum spools continues at CMTF.
PIP-II Injector Test
Running well, all RF components operating in CW mode, working on getting higher power beam to dump, doing machine protection and studies. Meson processed spoke cavity 112 (went well), next cavity will be “fully loaded” (high powered coupler), will see how HP processing goes.
Alignment
No report.
Controls
Nothing to report. Work in progress - cause/fix for FE reboots.
Cryo
No report.
ESH&Q
We have started a review of the Radiation Work Permit system. During a tour it was noted that several personnel did not have the correct PPE on for a tour or for work according to the RWP.
Remind personnel to complete the RWP, all fields Proper PPE, level 1 for tours and walkthroughs only, Level 2 for any work where you might be beamline components Describe the activity briefly in the sign off sheet. Do not put Fishing or Party Hard.
EE Support
Many details covered in systems reports. LRF2 tech swapped out Marx cells, LRF3 swapped broken Marx cell, swapped out DC correctors and modified in MI-8, also fixed some IP cables (835,836,838), supported kicker removal @ MI52 and did MIPS replacement mostly at MI-60, misc PMs on various ps.
Muon: repairs, PMAG (soft ground fault, replaced SCR), made mod on Lumina PS (on lens supp), AP50 subst., in P1 P2 P3 line made some repairs, on Muon campus replaced a control relay in PS, also lens PMAG pulsers control card needed to be reversed to earlier version.
MT5EL in SY needed PLC replacement. Want to do some LOTO training during BNB downtime. (today:10:30)
Instrumentation
Calibrated toroids at MI-40. BPM work attemped but need to modify tool for cable disconnect.
Mechanical & Fluids
MSD Machine Reports (Mechanical/Vacuum/Fluids):
Proton Source (Kubinski):
Wednesday - two 361 turbo pumps were installed on Source “A” LEBT. Test station klystrons were swapped. Fluids (Wallace):
On Wednesday, a new LCW pump on the LINAC Debuncher Skid was successfully installed and is in standby mode ready for operation. On Friday morning, a major water leak was reported on LRF4 RF skid. LCW supply hose on the LRF4 power amplifier filament failed. A patch and clamp was applied which slowed the leak down to a drip about every 60 seconds. The hope is that it holds until our recently ordered refurbished replacement hoses arrive, otherwise all our other systems look good.
MI/RR (Juarez):
Wednesday - Upon completion of Septa Ion pump installation, kicker removal, beam pipe installation, and RGA assembly installations, leak tests in the 520 area were performed a reading of 2.0 E-10. No leaks were indicated. IP’s were turned on and equipment removed from the tunnel. Thursday and currently - Vacuum bursts along MI and F0 portion of the P1 line. Vacuum recovering acceptable. Fluids (De Leon):
MI pond pumps switched to high speed (60 hp mode) summer mode A1 Pond Pump tested successfully. Bypass pump to reflecting pond. Main pond pump is off under configuration control. Leak on MI-40 Lambertson (section 624) inspected. Short term solution: Water routed away from the Lambertson using plastic. Long term solution is to pull Lambertson out in aisle and implement elbow assembly repair.
Beamlines (Vrbos):
Wednesday –
Performed vacuum leak checks in Muon Campus, D30, sector. Enclosure gate repaired between enclosure B and C. Blower station maintenance performed in G1 stub. Thursday and currently - Vacuum bursts along MI and F0 portion of the P1 line. Vacuum recovering acceptable. Did not get to inspect/tour F2 Sector for shutdown preparations
Fluids (Rivera/Clemons):
Performed water leak inspections/searches along external beamlines and switchyard. All installed magnet leak patches appear to be holding. THE DIPOLE 201-12 at the Enclosure C leak was sizable. Temporary patch applied, holding for now. Will be monitoring the Remnant LCW System
Fluids (Non-Machine Specific) (Rios/J. Todd):
FAST – Continued with IOTA project. Successfully performed low pressure gas test, held at 15 psig. Filled with LCW and started hydrostatic test. System held pressure of 150 psig for 1/2 hour. Found leak at girder 9 union, and relief valve I installed began to weep prematurely. Repairs made. Second hydrotest to be performed today, Friday. - Sehnal CUB – No LCW make-up needed today – John Todd
RF
