This particle (neutralino) is a good
candidate for the universe dark matter
Neutralino mass can be measured to 10 ? SUSY
discovery and neutralino mass measurement at LHC
can solve problem of universe cold dark matter

LHC Schedule

• A CRAG (Commissioning and Running Advisory Group)
  meeting was convened on 1st September, with
  participation of all its members (J Engelen, L
  Evans, S Myers, M Della Negra, T Nakada, J
  Schukraft, Peter Jenni, M Ferro-Luzzi, and M
  Mangano)
• L Evans confirmed the June LHC installation
  schedule, being very confident that the recent
  months have shown that the milestones will be
  reached
• S Myers was cautious, but commented that it is
  realistic to plan for a couple of weeks of 900
  GeV collisions in 2007
• The plan is to have the machine on open access
  January-March 2008, and have then the experiments
  closed again on 1st April 2008, followed by a
  few (3) weeks of controlled access
• The working schedule has then as target date for
  first 14 TeV collisions the last week of June
  2008 (obviously not a hard date)
• The experiments were asked to present at the next
  CRAG (no date yet, maybe early October) their
  wishes for the 2007 run
• Note S Myers has accepted to give a
  presentation on Friday morning

• Dear Ming and Ting-Yang, 
• Attached is a picture of the ATLAS Forward
  Calorimeter FCal3C Module. This module, built at
  Carleton University in Ottawa, Canada and now in
  our clean room at CERN, contains approximately
  half Chinese Tungsten Rods. Recent capacitance
  measurements confirm the dimensional Quality
  Control measurements that these rods are of
  excellent quality. These rods, which form the
  inner electrode of each of 8200 ionization gaps
  in each of two modules, are crucial components of
  the ATLAS Detector and are perhaps the hardest to
  produce with the necessary parameters. All
  indications are that this module will be a superb
  device within the ATLAS Detector.
•  
• The picture is taken in the Jura-side clean
  room in the North Area at CERN. The cabling of
  the module is just starting.
•  
• Best regards,
• 
  John Rutherfoord
