Minutes of the BEAST meeting
Friday November 6th 12:00 JST
We reviewed the readiness of BEAST and status of the installation.
Organization:
Please let me know your long term KEK travel plans and availability for BEAST
shifts. I will then begin to prepare a BEAST shift schedule starting
from December 1.
General:
Haba showed a drawing of the concrete minishield
and reminded us that it will be installed November 11-13. This will
make access to the BEAST more difficult.
The recabling on the BEAST side is now done. The DAQ side recabling
is being finished and the power supplies remounted. A patch panel for
BEAST power is being prepared. A rotating beacon was added to the
BEAST detector to signal the presence of high voltage. After the recabling
work is completed, there will be more complete testing of the
readout and DAQ.
A first look (discussed in e-mail from Gary) shows that it looks good.
Work to establish the trigger using the beam RF signal is also needed.
SVD:
The SVD group has been very busy debugging the BELLE SVD detectors
and readout. One of the two BEAST SVD ladders will be installed soon.
However, cables, VME crate and readout modules are not yet available.
CsI:
The CsI crystals will be installed starting on Saturday. One PMT for
the pure CsI crystals is broken.
DAQ:
Sakai reported that
there is a problem with the new CPU boards that allow communication
with the accelerator computer. It may be necessary to switch back
to the old CPU boards. Sakai also requested more details on the
parameters to be extracted from the KEK-B NSM (Network Shared Memory).
Connection of the BEAST DAQ to Tsukuba B-3 is also needed.
Simulation:
Rodriguez, Swain and Yamamoto are almost done with
updated background predictions.
