Abstract

Abstract— We develop a concept of the CW proton linac with the parameters of 13 MeV 162.5 MHz 5 mA. This linac designed for compact neutron source DARIA is based on the linac designed for the project BELA. The different linac layouts were considered. The most perspective linac layout includes Radio Frequency Quadrupole (RFQ) and Drift Tube Linac (DTL) sections with 6D beam matching between them. The drift tube linac section has a modular structure and consists of the separated individually phased IH-cavities with beam focusing by quadrupole magnets between the cavities. This DTL structure provides linac compactness, tuning and commissioning “cavity by cavity”. Results of the beam dynamic simulation and radio frequency parameters of the linac cavities are presented.
