Abstract :
The Japan Atomic Energy Research Institute has been proposing the Neutron Science Project (NSP). The joint project of the NSP and the JHF of KEK is under discussion. The new project makes use of the R&D results of the NSP and the JHF. The R&D activities of the proton accelerator at JAERI will be presented in this paper. The development work and characteristics measurements have been made for the low energy components of the linac; performance tests of a negative hydrogen ion source, development of an integrated type RFQ and high duty factor power tests of a DTL model tank. A superconducting linac is a main option for the high energy part of the linac. Vertical tests of a single cell superconducting cavity have been made. The maximum peak surface fields of 44 MV/m and 47 MV/m have been achieved for β=0.5 and 0.89 cavities, respectively. A 600 MHz IOT RF source has been manufactured and dummy load tests at 35 kW CW have been successfully conducted
