Minutes of the BEAST meeting
Friday October 2nd 12:00 JST



  • Diodes:

    Mosfets and RTDs were reported to be okay by Leon and Ascelin. All the diodes, 12 modules (24 diodes) are all tested to be okay.

  • Drift Tubes :

    Drift chambers (pulses) are essentially functional, but there are some time-dependent and e-hut/module dependent problems for a few channels. We have identified most of sources, and eliminated some. Other problems will be sorted out in coming days. Haba San will try to prepare some lead shielding for Beast preamps. Sahu will make some source holders for Cd sources.

  • CsI(Tl) :

    CsI group is working on their DAQ for Beast CsI. Crystals will be available by end of Oct. Installation will be early Nov.

  • KEK-B :

    We requested Funakoshi San for the following : (i) a Beast lattice that we can start with. The lattice will be finalized by end of Oct. But before that, he will provide a working(approximate) version soon. (ii) to prepare a BPM and an RF pick up for Beast trigger.(iii) to provide data file format for magnet and vacuum parameters. These will be used and exchanged in KEKB-BEAST database. Now the priority is software - simulation, analysis and KEKB--BEAST interface.
