Abstract

The present status of the development of the 1-GeV proton linac for the Japanese Hadron Project is reported. The linac is composed of an H^- ion source, a 432-MHz RFQ (radio-frequency quadrupole) linac (3 MeV), a 432-MHz drift-tube linac (148 MeV), and a 1296-MHz high-β linac (1 GeV). An electroforming method for sealing a 432-MHz drift tube was developed. Results of field measurement are presented for a cold model of a drift-tube linac. The high-β linac is described in detail. A study of an annular-coupled structure indicates that this structure is promising for the project
