Analysis
Grant-in Aid money application
for detecor R&D
(a few 10 M\ for 2 years)
A guess!
Grant-in-Aid money application for experiment
(~300 M\ for 5 years)
 Very
dependent on the K1.1-BR beam installation
(5 years)
Grant-in-Aid application in Japan
 We will make a 5 year plan for 2008 to 2012 for ~ 300 kYen.
• Active polarimeter
• Muon field magnet
• CsI(Tl) readout
• Total assembly
• Electronics and DAQ
• Some fraction of Target and Tracking
• Operation money (travel, meeting etc.)
 Transfer of the SCM and He cryogenic system are not included.
 Application deadline is the end of October at KEK
 We will describe all the details of the total project . It is very
desired that we can show the international cooperation in detector
upgrades.
International cooperation
• Memorandum of Understanding (MoU):
• Now in preparation process between TRIUMF /JPARC
and INR/JPARC
• Responsibilities of both sides
• It will facilitate the installation of the beamline
• How about MIT and other universities?
– Letters from the J-PARC center director enough?
• Contribution tot the branch part of K1.1-BR from Canada?
Job assignments and schedule (1)

KL/K1.1 installation according to the PAC
recommendation
• This plan will be presented to the next PAC meeting in
January. There we have also to make our E06 progress
report.
