Presentation Transcript

  1. LHC Sector 45 - ∆P=f(t) “Process instabilities” every 2 weeks ! 1 2 3 4 5

  2. Comparison of various runs Today’s limit, corresponding to 30 mbar - 2.0K for saturation temperature, and 2.1K for magnets! Cool-down IT_L5

  3. LHC sector 23, treated ? 16 Mar au 24 Mar Nice tendency ! Treated ? To be confirmed on longer period …

  4. After Easter • P4/sect45: (≈ 18hrs) stop CC - warm-up filter > 80K - re-cooling Access in US/UX45 to check some settings • P6/P8 being evaluated, as we should try to be able to operate with confidence until next Technical stop… • P18/Sect12 and P2/Sect23: Not an issue (so far)
