Abstract

Abstract

The China Spallation Neutron Source accelerator is designed to accelerate proton beam pulses to 1.6 GeV at 25 Hz repetition rate, striking a solid metal target to produce spallation neutrons. The accelerator provides a beam power of 100 kW on the target in the first phase. The linac is designed with beam energy of 81 MeV and a peak current of 15 mA. It consists of RFQ, two bunchers of medium energy beam transmission line, four DTL tanks, and one debuncher of linac-to-ring beam transmission line. Correspondingly eight online RF power sources are used to power these accelerators. So far, all RD prototypes of the CSNS linac RF power sources have been completed, and the performance meets the design requirements. Mass production, equipment installation and commissioning are still under way.
