中国散裂中子源伴生质子束实验平台及其应用

Associated Proton Beam Experiment Platform and Its Applications at CSNS

基于中国散裂中子源(China Spallation Neutron Source,CSNS)建设的伴生质子束实验平台(associated proton beam experiment platform,APEP)主要用于宇航器件及设备的辐照损伤研究。质子能量在10~80 MeV之间连续可调,束流能散小于10%,束斑尺寸和束流流强也能够根据实验需求进行调节。自2021年10月投入运行以来,APEP已经开展了电子元器件辐照损伤实验、探测器标定实验、各类材料辐照损伤研究等百余项多学科实验研究,为我国多学科特别是辐照损伤效应领域的科学研究和应用研究提供了一个重要的质子束实验平台。

As an experimental platform mainly used for irradiation damage research,the associated proton beam experiment platform(APEP)is constructed at China Spallation Neutron Source(CSNS).The beam energy of APEP ranges from 10 to 80 MeV and the energy spread is less than 10%.Furthermore,the beam spot size and beam intensity can be adjusted to meet experiment requirements.Since its commissioning in October 2021,more than a hundred experiments including electronic irradiation damage tests,detector calibration,and material irradiation damage have been completed at APEP.APEP provides a powerful platform for scientific and applied research in the field of irradiation damage effect in China.In this paper,the construction principle and key parameters of APEP is reviewed,and its application direction is pointed out.
