Creation of New Budget Schemeg
JAEA– At the Government level, an establishment of a new law, which
was adopted at SPring-8, will be applied for J-PARC from JFY2011.JFY2011.
– This new scheme will cover a) operations for Linac and 3 GeVb) b li t ti d i t f t b lib) beamline construction and maintenance for neutron beamlines
– The Government controls directly this funding.– Usage open for universities, institutes, industries, internationals.g p , , ,
KEK– The normal operational budget scheme is still used for KEK.The normal operational budget scheme is still used for KEK.
However, the normal operation budget decreases every year.– Competition with B-Factory (or, in particular, with Super B, if it
were ever constructed) will be an issue for the future

level.

New members were l d i N belected in November
of 2007.Representatives from fourfrom four communities are included.Roadmap of the future J PARC willfuture J-PARC will be discussed at this committee.
– Discussion items b thi ittby this committee were re-identified.
– The committee will start intense discussions fromdiscussions from February about future plans of the J-PARC.

Phase 2 for J-PARC will be discussed at this Committee
Major Upgrades Items (from 2008 IAC) j pg ( )
Neutrons and MuonsNeutron equipments: How to fill the 23 beamlines (so far about ten– Neutron equipments: How to fill the 23 beamlines (so far about ten were funded).
– Muon equipments: Among four beamlines, only one will be in operation in 2008. Others have to be funded.
Hadrons– Must construct several kaon beamlines plus a primary beamline.– Hadron hall expansion: Necessary to accommodate many user
groups.– Any future possibilities recommended from PAC.
Neutrinos– Power upgrade.– The 2 km detector for T2K.
Nuclear Transmutation– The major item for Phase 2.
Others– Energy upgrade to 50 GeV
40
– Energy upgrade to 50 GeV.– Third extraction line or Fast Extraction at Hadron Hall?– Polarized protons, heavy-ions, ….

Achievement
Milestones achieved during the past one year– Construction for both equipments and facilities: Almost on schedule.
Production of neutrons and muons, 30 GeV acceleration and extraction to the Hadron Hall
Neutrino construction will be completed by the end of March of this year.
– Started a usage of the MLF facilitiesStarted a usage of the MLF facilities.
Budget– Operational money for JFY2009 was funded, to allow 110 day
tioperation.
– New budget scheme for JAEA started. Two neutron beamlines were funded.
– Supplemental budget funded for the energy recovery for Linac and K=1.1 beamline for Hadron.

Issues
Stability of the accelerator
– RFQ, RF (Finement), Power Station, Beam Loss
Intensity growth of the accelerator
Need to create Accelerator Review Committee to review all– Need to create Accelerator Review Committee to review all needed items for the intensity growth to 1 MW.
– Several elements must be replaced and also must be newly constructed.
Spares
All items need spares Some critical items are say the– All items need spares. Some critical items are, say, the mercury target, RF systems, etc.
