Original plan for secondary line installation

1. Original plan for secondary line installation

2. Hadron hall secondary beamlines Hadron hall beamlines in Phase1 ① ② ③ ④

3. Other approved experiments E05, E13: stage-2 E07, E19, etc: stage-2 Hyper-nuclear exp. Using SKS as Day-1 from 2009 @K1.8 E15, E17: stage-2 Kaonic nuclei exp. as Day-1 @ K1.8BR E14 :stage-1 KL->p0nn-bar @K0 E06 @K1.1BR Three secondary lines run simultaneously

4. Time schedule of E06 A guess! • Very dependent on the K1.1-BR beam installation

5. 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.

6. 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?

12. 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
