Minutes of the BEAST meeting
Friday July 17th 12:00 JST

  • Schedule:
    Here is the tentative plan which may be modified as more information about the accelerator schedule becomes available.
    Aug 20thBEAST structure and detector components shipped to KEK.
    Aug 25thSahu and Rosen go to KEK
    Aug 26-Sept 10 BEAST Assembly and Installation at KEK
    Aug 30 DAQ components shipped to KEK
    Early Sept Moffit and Gordon arrive at KEK for DAQ installation
    Sept 14-24 BEAST system test.
    Sept and Oct GEANT Simulation Work and Updated Background Predictions
    Oct 12-late JanAccelerator Commissioning
  • Manpower:
    Lots of help will be needed for BEAST shifts. An initial group of shiftakers has been identified:

    Melbourne: Moffit*, Gordon*, and one additional student (DAQ experts)
    Hawaii: Sahu*, Casey, Swain, Fang, Browder, Varner.
    Cincinatti: Satapathy* (CsI(Tl) expert)
    Novosibirsk: Kuzmin* (CsI(Tl) expert)
    KEK: Bozek, Haba, Tsuboyama (SVD expert)
    Taiwan: Wang* and others (EFC experts)

    * indicates a visiting person in residence at KEK for the duration of BEAST

  • DAQ:
    The Kinetics 3922 crate controller arrived in Melbourne. The interface board to the PC was purchased and was shipped to Australia.

  • Structure:
    Parts were ordered for the beampipe and BEAST support. Drift tubes are 90% complete. 50% are fully terminated with gas and electrical fixtures. CsI(Tl) clamps and supports are being fabricated. No Pb shielding will be used on the "endcap crystals". The SVD quadrant is being finalized.

  • Drift tubes:
    All PC readout boards populated (1/3 are tested). There are some discharge problems associated with humidity that are being worked on.

  • Diodes:
    Hawaii student Casey Law reported on the diode calibration work. The temperature calibration is ok (10/36 diodes tested). The radiation dose calibration is starting.

  • Beampipe:
    Tsuboyama reported on the cooling tests of the beampipe. Cooling is sufficient to dissipate the 200 W expected from HOM (Higher Order Mode heating) at design luminosity. Details are reported in his e-mail message. Note that the diodes in BEAST are mounted on an Al layer just above the beampipe to avoid temperature dependent shifts of the calibration.
