Minutes of the BEAST meeting
Friday August 14 12:00 JST

  • Schedule:

    Haba reviewed the current status of the schedule and the plan for installation. We are now preparing for the installation of a standalone version of BEAST and working with the assumption that KEK-B commissioning starts November 10th. Melbourne and Hawaii personnel are arranging travel and resources to be compatible with this schedule.

    Initially, the electronics stage and the base of the radiation shield (Yoshioka) will be prepared. Cable racks, power and network are being prepared. This work will be completed by the end of August.

    The BEAST "bed" and beampipe support will be shipped on August 24th. Beam pipe installation will be carried out by Sahu, Rosen and Haba in early September. This includes placement of the beampipe support and surveying/adjustement of the position. There will also be a check of the beampipe cooling. This work should be completed by September 5th.

    In parallel, the EFC installation is being prepared by the Taiwan group (M. Wang, Ueno et al). The EFC will be mounted on the final quadrupole (QCS) from August 26-31. Cabling and electronics are also being prepared.

    The BEAST detectors will be shipped August 31st. After completion of the beampipe installation, the inner BEAST will be installed starting September 5th by Rosen and Sahu. The outer BEAST, drift tubes and supports for the crystals, will then be installed September 5-10.

    This is followed by tuneup of the detectors, installation of the DAQ by the Melbourne group (starting September 9th) and then establishment of communication with KEK-B computers.

  • Personnel and Organization:

    Haba asked for a detailed breakdown of the tasks in the above items. Individuals for debugging the BEAST components at KEK were identified:

    Drift tubes (Sahu)
    Diodes (Sahu)
    MOSFETs (Moffitt)
    DAQ (Gordon, Moffitt)
    SVD (Tsuboyama)
    CsI(Tl) (Zhilich, Kuzmin)
    EFC (Ueno et al.)

  • DAQ:

    Moloney reviewed the current status of DAQ tests at Melbourne. The LINUX PC based readout system was used to successfully readout CAMAC ADCs and Scalers at a 1 kHz trigger rate. Details are in earlier e-mail message.

    Sakai reviewed communication with KEK-B. He and Yamamoto are developing a framework for communication with KEK-B and learning to transfer information to/from NSM (VME Network Shared Memory). NSM is connected to iocpytb3 (accelerator computer) and to the BELLE online network. By the end of August, a template program for extracting information from EPICs (accelerator database) will be written.

  • Structure and Construction:

    Sahu reviewed BEAST construction status. All elements of the structure and beampipe support will be finished by the end of next week. The diodes and MOSFET boxes are being finished. The diode PC readout boards will be ready by the end of August. KEK resources for BEAST detector operation such as low voltage power supplies (+-5 V, +-15 V, and 80 V), bubblers, flow meters, and gas tubing are being procured.
