摘　　要：The Xi'an Proton Application Facility(XiPAF)is a facility dedicated to the experimental simulation of the space radiation environment.The facility uses a compact synchrotron as its final-stage accelerator.The synchrotron can accelerate a proton beam from 7 to 230 MeV.Physical design results show that the radio frequency(RF) acceleration system should work in the frequency range of 1—6 MHz and provide a maximum voltage of >800 V.To dilute the strong space charge effect during the injection period,we also aim to achieve multiharmonic acceleration.A compact RF acceleration system loaded with magnetic alloy cores has been designed and developed to fulfill these requirements.The preliminary test results show that the system can work normally with a gap voltage of 800 V.With a further RF power upgrade,the voltage can be improved to >1:2 kV.The Xi＇an Proton Application Facility （XiPAF） is a facility dedicated to the experimental simulation of the space radiation environment.

To dilute the strong space charge effect during the injection period, we also aim to achieve multiharmonic acceleration. A compact RF acceleration system loaded with magnetic alloy cores has been designed and developed to fulfill these requirements. The preliminary test results show that the system can work normally with a gap voltage of 800V. With a further RF power upgrade, the voltage can be improved to 〉 1.2 kV.
