Message-Id: <200411040955.iA49tGgx024865@neutrino.kek.jp> Subject: Minutes of K2K Steering Meeting (Nov.04) Date: Thu, 04 Nov 2004 18:55:16 +0900 From: Takanobu Ishii <ishii@neutrino.kek.jp> ========================================================================= *General Report* ------------------------------------------------------------------------- As reported by Sato, a short off-direction beam study was done on Nov. 9 for a trial purpose. Some of plots were shown by Takubo. Next week will be devoted to the off-direction run. ========================================================================= *Schedule* ------------------------------------------------------------------------- ===Beam=== Nov.08(Mon) 9:00 Neutrino beam stops 9:00 ; Dump-mode-change by Hayato 9:00- Machine maintenance, horn maintenance 18:00- 12GeV MR tuning ~20:00 After beam channel tuning, neutrino beam starts ~20:00 ; Dump-mode-change by Ishii Nov.09(Tue)10:00-12:00 Ion source exchange(1->2), MR tuning (no nu beam) 10:00,12:00 ; Dump-mode-change by Ishii Nov.12(Fri)14:00-16:00 Ion source exchange(2->1), MR tuning (no nu beam) 14:00,16:00 ; Dump-mode-change by Ishii ===Detector=== Somewhen between Nov.08(Mon) 9:00-18:00 SCIFI cosmic-ray run ===Shift=== Nu-H shift of Nov.08-A should do a hardware check once and he is free. NH-CR shift of Nov.08-A is canceled. Shift time at KEK (SK shift is a little different) A-shift : 9:00-17:15 B-shift : 17:00-25:15 C-shift : 25:00-9:15(next day) ========================================================================= *Reports from each subcomponent* ------------------------------------------------------------------------- ===BEAM MONITOR=== (Sato) Muon noise studies on Thursday evening and Friday evening. The origin is not identified yet. The fraction of bad spills due to muon noises is about 10% for worst cases and about 1% on average (Oct 02 to Oct 24). Beam timing information problem on Friday, 4:45 and 19:25. Ion source down 4 times from 17 on Sunday to 9 on Monday (and more). Scheduled maintenance and accelerator studies from 9 on Monday to 9 on Tuesday. Beam has resumed at 13 on Tuesday. Off-direction beam study (for trial purpose) from 17 to 19 on Tuesday(Ishii et al.). Plans: 11/4- Muon noise study 11/8-12 Off-direction beam study ===MRD=== (Ishii) The MRD has been working well without any problem this week. ===1KT=== (Ryan Terri) The 1kton has nothing to report. The detector was working with no problems for the last week. (Ishii) Asia said that the beam timing is shifted by 25ns than nominal. It is still OK but close to the border. ===SCIFI=== (Iwashita) SciFi detector has been working without any problems. ===VETO=== (Nitta) No problem. ===SCIBAR=== (S.Yamamoto) SciBar had been working with no troubles. ===SK=== (Obayashi) o Status of last week Oct 31 2:40 - 4:02 One ID HV crate down Recovered by switch off/on Other period has been stable. ========================================================================= SUMMARY of NORTH COUNTER HALL SHIFT (K.
