Status of the Tokai Radioactive Ion Accelerator Complex (TRIAC)

Abstract

Tokai Radioactive Ion Accelerator Complex (TRIAC) constructed by High Energy Accelerator Research Organization (KEK) and Japan Atomic Energy Agency (JAEA) started to supply the 0.178 to 1.1 MeV/u radioactive nuclear beams (RNBs) for experiments since November 2005. The TRIAC facility is an Isotope Separator On Line (ISOL) based RNB facility, and uses a tandem accelerator (primary accelerator), an ISOL, a charge-breeder of electron cyclotron resonance type, and a heavy-ion linac complex (post accelerator). Several experimental studies have been performed successfully using ⁸Li beams with various energies. In order to increase the beam energy up to 5-8 MeV/u, it is planned to connect the heavy-ion linac to the superconducting linac existing at JAEA tandem facility.
