Abstract

Abstract:

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 16 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.
