Time schedule of E06

A guess!

Very dependent on the K1.1-BR beam installation

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?

• Tracking simulation and K-dif BG estimate (S.Shimizu, K.Horie)

• K0.8 beam line design improvement (J.Doornbos)

Beamline issues and next PAC

• IPNS/J-PARC starts to make a realistic plan of 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.– K0.8 beam optics optimization

– Target readout method, MPPC or PMT?

– Further study of systematic errors (down to << 10-4)

– High rate performance of the detector (in general?)

– Funding efforts/ international cooperation with MOU

Time schedule

• Application of the Tohoku beam time in Sept.• Application of Grant-in-Aid money in Japan : in October 2007 • Next PAC meeting : 7-8 January, 2008• Next TREK meeting : February, 2008• Next next TREK meeting : where and when?
