简介:摘 要: 应相关建设安评、环评、稳评以及职业健康评估的要求。电子加速器设计过程中即应对其辐射情况进行分析。针对电子能量为40-95MeV可调的光阴极微波电子直线加速器,对其射源项进行分析,并讨论了可能的额射防护措施的效果。采用蒙特卡罗软件FLUKA对电子束流和加速器进行建模,通过模拟计算发现。加速器产生的等效剂量分布主要位于废束桶中,废束桶以外辐射剂量迅速下降,在电子加速器实验大厅四周设置混凝土墙体的情况下辐射等效剂量率将随墙体厚度迅速下降。若混凝土墙体厚度设置为1m.则墙体外工作人员所在区域辐射等效剂量率不高于1Sv/h量级,能够有效屏蔽加速器产生的电离辐射,给工作人员提供有效防护。研究方法及结果对同能区同类型加速器建设中的辐射分析及辐射防护评估具有一定的参考价值。

简介:针对DC/DC的质子位移效应,选取具有抗TID能力的DC/DC器件作为试验样品,在3MeV质子辐照条件下获取了器件的失效位移损伤剂量.结果表明,DC/DC功能失效是PWM控制器输出异常导致的.通过等效^60Coγ辐照及退火试验,排除了TID效应的影响,确定器件功能失效是由位移损伤引起的.高温退火后器件功能恢复,并立即对该器件进行了测试.结果表明,输出电压、电压调整度、负载调整度、交叉调整度、纹波及负载跃变时的输出电压均大幅衰退.利用这些敏感参数,获取了位移损伤导致的电源性能衰退模式.根据位移损伤缺陷类型及退火温度,分析了DC/DC的退火规律,可为DC/DC质子辐射损伤模拟试验方法的建立及其空间应用提供依据.
