Status and Test Results of HPRF System for PEFP

The PEFP 20MeV proton accelerator is composed of 3 MeV RFQ and 20MeV DTL and two sets of 1 MW, 350 MHz RF system are required for each accelerating structure. The high power RF system for 3 MeV RFQ was already installed and operated to drive the RFQ. The klystron was tested up to 600 kW itself and operated in pulse routinely. The HPRF system for 20 MeV DTL which consists of 4 tanks was installed, and the RF test for 4 tanks has been carried out. Four RF dummy loads for absorbing RF power reflected from each accelerating structure were designed and manufactured. In this paper, the status and test results of the RF system for 20 MeV proton accelerator are discussed.
