摘要：This paper presents the design of a compact proton synchrotron, including lattice structure, injection system and extraction system, for radiation applications. The lattice is based on a DBFO cell and shows good properties like small β_（max） and decent kick arm. radiation applications require relative strong and continuous beam,so we propose strip injection and resonance extraction for the design. A phase space painting scheme is designed and simulated by ORBIT. The scheme achieves good uniformity in phase space. The extraction system is designed and optimized by multi-particle tracking.

摘要：The Xi'an Proton application Facility(XiPAF)is a facility dedicated to the experimental simulation of the space radiation *** facility uses a compact synchrotron as its final-stage *** synchrotron can accelerate a proton beam from 7 to 230 *** 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 *** 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 *** preliminary test results show that the system can work normally with a gap voltage of 800 *** a further RF power upgrade,the voltage can be improved to >1:2 kV.
