Development of superconducting cavities for high intensity proton accelerator at JAERI

摘要

The Japan Atomic Energy Research Institute (JAERI) is proposing a high intensity proton accelerator for the Neutron Science Project. A superconducting (SC) RF structure is the main option for the high energy part of the linac. Design and development work of the SC proton linac is in progress in JAERI. Three single-cell SC prototype cavities were fabricated and their performances were tested. The test results were good enough to apply to the SC linac. This paper describes the present status of the design and development work for the SC proton linac.
