MI/RR Machine Report Ming-Jen Yang Jan 08, 2016
Weekly summary, RR for NUMI Jan. 08, 2016
Weekly summary, MI/RR for Switchyard Jan. 08, 2016
MI weekly Downtime SYSTEMS Downtime refined by MAINJECT, Beam_Inhibit_Failure from 1/1/2016 08:11:50 to 1/8/2016 00:00:00 (159.8 hrs.) RF (22.2%) 2 min. Power_Supply (44.4%) 4 min. Vacuum (33.3%) 3 min. RF Vacuum Power_Supply Jan. 08, 2016
RR weekly Downtime SYSTEMS Downtime refined by RECYCLER, Beam_Inhibit_Failure from 1/1/2016 08:11:50 to 1/8/2016 00:00:00 (159.8 hrs.) RF (8.9%) 4 min. Diag/Inst (91.1%) 41 min. Diag/Inst RF Jan. 08, 2016
Shut down on 12/30/2015 Fixed RF station #11 and #12 Found dripper magnets Dipole upstream of Q122 Same drip location found in 2014. Quad 503 manifold. Small drip to ground Quad 504 & Quad 508 Wet but no dripping. Jan. 08, 2016
Issues I:VT851 Appears to be just MADC read-back problem. R:QT309 Scaling for G and H table has been corrected. Investigation on toroid calibration continues R:TOR853 and I:TOR806 Kickers are ruled out as the cause. Waiting for new RR DCCT Jan. 08, 2016
RR beam loss Ring losses LI421/LI425 Scan 421 Scan 425 Jan. 08, 2016
PMT signals at 421 1st turn 2nd turn 3rd turn 4th turn 5th turn 5 turns Jan. 08, 2016
RR beta function, as is Jan. 08, 2016
RR beta function, with 30 QT fix Jan. 08, 2016
Studies Tune scan Study the effect of fifth integer resonance. Electron cloud Investigate strip-line detector signal tail Not consistent with e-cloud signal. Distribution box also is not source of tail. Beta wave fix TBT data taken with correctly set 30 QTs. Study to compare loss locations with and without the fix. RR 4+6 slip-stacking Made operational during day time. Tuning continues. Jan. 08, 2016
