LINAC COMPLEX FOR RI BEAMS IN JAERI-KEK JOINT FACILITY

Construction of JAERI-KEK joint facility for RI beams based on the ISOL method has started from 2001at the tandem cite at JAERI-Tokai. Primary protons are accelerated by the existing tandem accelerator, and produced RI beams are accelerated up to 1 MeV/u by linacs which had been operated at KEK-Tanashi till 1999. They can be connected to the existing superconducting heavy ion linac together with an additional 2-MeV/u IH linac. This extension provides RI beams with higher energies above the Coulomb barrier.
