摘　　要：针对抗瞬态辐射对宽剂量率范围、弱电磁干扰、精细测量等瞬态剂量率效应试验评估需求,开展激光瞬态剂量率效应的激光注入控制及定量模拟试验技术研究,研究脉冲激光与“强光一号”加速器剂量率等效试验机制,结合激光辐照过程中的能量传输模型进行激光有效能量计算,给出激光能量和γ射线剂量率的定量关系,形成直径为3 cm、均匀度达90%的大尺寸高均匀度试验辐照光斑,及等效剂量率大于1.2×10^(12) rad·s^(-1)的激光定量模拟瞬态剂量率效应试验能力。对多款不同类型器件开展了激光和“强光一号”加速器对比试验证明了该技术的有效性,可为抗核辐射发展提供便捷、精细、充分的激光试验技术支持。A novel method is proposed for the evaluation requirements of transient dose rate effects such as wide dose rate range,weak electromagnetic interference,and fine measurement against transient radiation.Research on laser injection control and quantitative simulation testing technology for laser transient dose rate effects(TDRE)is carried out.The equivalent testing mechanism of pulsed laser and"Qiangguang-Ⅰ"accelerator dose rate is studied,and the effective energy of laser is calculated based on the energy transfer model during laser irradiation.The quantitative relationship between laser energy and gamma ray dose rate is given,forming a large-sized high uniformity experimental irradiation spot with the diameter of 3 cm and a uniformity of 90%,the ability to quantitatively simulate transient dose rate effects of laser with an equivalent dose rate is greater than 1.2×10^(12) rad·s^(-1).The comparative experiments of laser and accelerator on multiple different types of devices have proven the effectiveness of this technology,providing convenient,precise,and sufficient laser testing technology support for the development of nuclear radiation resistance.
