Title: CSNS LINAC RF SYSTEM DESIGN AND R&D PROGRESS
Abstract: China Spallation Neutron Source (CSNS) is determined to be constructed in Dongguan, Guangdong province of south China. Now its design and R&D are in progress in IHEP, Beijing. The 324 MHz rf linac is designed with beam energy of 81 MeV and a peak current of 30 mA [1]. In the klystron gallery, five klystron power sources will be used to power the RFQ and the four DTL tanks, and three solid state rf amplifiers will drive two MEBT bunchers and a LRBT debuncher. Now we have already made some progress with some key technologies for linac rf system. The digital low level rf (LLRF) prototype was already developed and successfully applied in beam commissioning of the ADS (Accelerator Driven Subcritical system) 3.5 MeV RFQ accelerator at peak beam 46 mA, beam duty 7% [1]. A proposed new type of power supply, 100 Hz ac series resonance high voltage power supply, passed acceptance test and a satisfactory test results was obtained. R&D of crowbar and modulator has gotten good performance test data. In this paper, a description of these linac rf R&D activities will be briefly presented.
