摘　　要：中国原子能科学研究院回旋中心正在研制一套中能质子辐照装置,提供能量范围在10MeV^50MeV的质子束流, 以模拟对航天器有重要影响的空间质子辐射环境。在50MeV紧凑型回旋加速器的基础上, 设计了质子束流输运系统, 将 回旋加速器引出的质子束流,通过降能器等元器件调整到用户所需能量, 降能后的质子束经过聚焦、 偏转后传输到用户终 端。为在靶上得到均匀的大直径束斑,束流线上安装了旋转扫描磁铁, 将靶上的质子束流均匀扫开, 最终在靶上得到能量 10MeV^50MeV可调,质子流强最大10 A,尺寸20cm×20cm的束斑。The cyclotron Center at CIAE is now developing a medium-energy proton irradiation device that provides a proton beam with an energy range of 10 MeV to 50 MeV to simulate a space proton radiation environment,which has a signif icant impact on spacecraft.Based on the 50MeV compact cyclotron a proton beam transport system is designed.The proton beam extracted from the cyclotron is adjusted to the energy required by using the degrader,then the proton beam is bended and focused to transmitted to the user terminal.In order to obtain uniform largediameter beam spot on the target,a wobbling magnet is installed on the beam line to uniformly sweep the proton beam on the target and f inally obtain the proton beam with energy of 10MeV-50MeV,current of 10μA and beam spot of 20 cm×20 cm on the target.
