Presentation Transcript

  1. 15 m Long Shaft : Field Quality (incl. b1) @ cold 90 MB to end 2003 ; 23 in 2004 Foreseen @ Chamonix : 1/3 (400 / 1150) Issues : Shaft insertion/removal Backlog (still 120 MB) : logistics and Rocla (Duration of measurement) (Data reduction (better in Sept, then in 2005)) Strategy as long as less than 10.5 MB/week (now 7 MB/week) 2 MB/week : loadline & LHC cycle Extended tests when not limiting the test rate should cover 50 MB / 1000

  2. F.Q. Measurement of MB’s in 2004

  3. SSW (Stretched Wire) @ cold Only system measuring a1 (tilt) Equivalent to Long shaft for b1 in static (Loadline) Need : W/C correlation = 0.3 mrad  0.05 mrad (only 7 MB => improve) Issue : 2 SSW availble and heavily used (SSS) Learning phase for normal operation Proposal : wait for 3rd system (fall 2004)

  4. Field Direction @ Room Temperature Present : (more than) 1 MB/day in SMA18 with SSW Issues : No SSW available (after 8 more MB in SMI2) DIMM calibration/stability to improve (w.r.t. SSW) Limited by logistics Need ? Strategy : install asap F.D. with DIMM in Industry measure as much as possible in SMA18 in the meantime
