3. 29 September 2006M.Sakuda NuFact06 Construction Schedule Status Mile Stones Start the Linac Beam Commissioning: Dec., 2006 Start the RCS Beam Commissioning: Sep., 2007 (start to transport the beam from the linac to the RCS) Start the MR Beam Commissioning: May, 2008 (start to transport the beam to MR and/or MLF) Start the Experiment sometime in JFY2008 3

4. 29 September 2006M.Sakuda NuFact06 Beam Power Goal MR: 0.75 MW (50 GeV, 15  A), slow and fast extraction for nuclear and particle physics experiments RCS: 1 MW (3 GeV, <1  s, ~ 25 Hz) for spallation neutron source 4 Ring Final Goal (Phase II) Phase I Goal MR: 0.6 MW (40 GeV, 15  A) RCS: 1 MW (3 GeV, 333  A) Phase I 0 Goal MR: 0.36 MW (40 GeV, 9  A) RCS: 0.6 MW (3 GeV, 200  A) In order to increase the MR beam power beyond this level, various operational modes have been proposed, including the increase in the number of MR bunches, the increase in the MR repetition, and so forth. However, the accomplishment of the Phase I 0 Goal with the robust, reliable hardware is most important. Then, the attempts of various operational modes will be realistic, and efficient.
