Presents: GB, CB, SF, MG, JJ, WH, VK, AK, YP, SR, TR, GRdM, TW

• Follow-up of actions from previous meetings
  • Complete comparison between model from database and model used by collimation team (Action: JJ+SR).
    • First detailed verifications started. Strategy for the checks should be agreed (Action: MG).
  • Beam 2 in MAD-X -> (Action: MG)
    • The tests are still in progress: new results will be presented at the next meeting.
  • Feedback on
    • Chamonix organisation
      • Proposals for subjects, feedback on the sessions should be sent to MG.
    • Kicker timings (MKQ, MKA)
      • MG discussed with J. Uythoven to set up an official approval procedure. The feedback received should then be entered in EDMS.
    • Separation of the Technical and Office Computer networks
      • No feedback received so far: MG assumes that impact on MD activities for LOC members will be the same as for other sections, e.g. LII.
• Report from meetings
  • SLM -> MG
    • A revised schedule for the Group Meetings is presented (pdf file)
  • MEB -> SF
    • MBs allocation is slowing down.
    • SSS have top priority concerning installation. 100 SSS have been allocated so far.
    • Three special SSS will be allocated in the next days.
  • Sector test meeting -> HB (pdf file)
    • It is proposed to define a list of people from LOC, which would like to participate in the sector test.
    • Feedback should be given concering the proposed measurements during the sector test.
• Conclusions on the crossing schemes for IP8  -> WH (pdf file)
  • Due to aperture issues for one spectrometer polarity, the option beta* = 1 m is dropped.
  • The minimum beta* will be 2 m (after the meeting WH confirms that under the conditions foreseen for the LHC commissioning, this beta* is compatible with the requirements on the luminosity for LHCb).
  • The spectrometer should be ramped, starting from zero or a small value.
• Aperture specification for the triplet quadrupoles -> JBJ
  • This point is cancelled due to a clash with the WGA meeting
• Progress in the implementation of solenoids in MADX -> HB (pdf file)
  • A number of discussions took place: the proposed implementation requires some further analysis. It is proposed to resume the discussion with FS once he is back for FNAL.
• AOB
