In J-PARC, possibility of a future heavy-ion program has been discussed. In particular, we discuss heavy ion accelerator schemes, physics goals, and experimental setups. There are two physics subjects included in the program. One is a low energy heavy ion physics, to study unstable nuclei with the linac beam at 1-10 AMeV/c, and the other is a high energy heavy ion physics to explore nuclear physics at a high baryon density with the Main Ring beam at 1-10 AGeV/c. In this work, the latter is presented. In particular, we focus on measurements of lepton pairs in order to study high baryon density, and we also search for exotic hadrons and nuclei. We show a preliminary heavy-ion scheme and design of a heavy ion spectrometer.

R&D of high power density negative ion beam acceleration has been carried out in JAEA to realize ITER neutral beam accelerator. For long pulse acceleration at high power density, reduction of acceleration grid heat load is necessary. One factor of the grid heat load is secondary electrons emitted from electron suppression grid (ESG) by means of direct interception of negative ion beam. Aperture size of ESG is enlarged from 14 mm to 16 mm to reduce direct interception on the ESG. By enlarging ESG aperture, beam current increased 10% at high current beam and total acceleration grid heat load reduced from 13% to 10% of input power at long pulse beam. Beam acceleration up to 60 s which is the facility limit, has achieved at 683 keV, 100 A/m
of negative ion beam.
