Acceleration of heavy ions by the JAERI tandem superconducting booster

Abstract An independently phased heavy ion linac composed of 46 superconducting quarter wave resonators has been built as a booster for the tandem accelerator at Japan Atomic Energy Research Institute, Tokai. Several kinds of heavy ions from Si to Au have been accelerated. The performances of the resonators and the cryogenic system, the method of setting resonator phases and the results of the beam acceleration tests are described.
