RD STATUS OF SUPER-CONDUCTING PROTON LINAC AND THE KEK/JAERI HIGH INTENSITY PROTON ACCELERATOR PROJECT

摘要

R&D work of a super-conducting proton linac has been continued since 1995 in JAERI for the neutron science project and the current KEK/JAERI high intensity proton accelerator project. In the cavity development work, we obtained good performance, high field and high quality factor. As the next step of the R&D, a prototype cryomodule was fabricated. The cooling and high power RF tests of the cryomodule were performed successfully. The RF test is being continued to obtain stable accelerating field in the pulsed operation. In the high intensity proton accelerator project, the super-conducting linac is planned in the energy region from 400 to 600 MeV and the beams will be delivered towards the transmutation experimental facility (TEF). TEF consists of two facilities; the transmutation physics experimental facility (TEF-P) and the target test facility (TEF-T). This paper provides the R&D status of super-conducting proton linac and the high intensity proton accelerator project concerning the super-conducting linac and TEF.
