【摘要】 基于光纤传输的强电磁脉冲传感器具有良好的抗电磁干扰性能。核爆炸以及核爆炸模拟装置激励的电磁脉冲是γ射线与空气分子作用散射的康普顿电子激励的,γ射线能穿透屏蔽壳体进入传感器内部,作用在集成电路上会产生干扰、闭锁或毁伤等效应,影响传感器的性能指标。介绍了在强光I号加速器上开展强电磁脉冲传感器γ辐照效应实验方法。实验结果表明该传感器的γ剂量率干扰阈值为2×106Gy/s。更多还原

【Abstract】 The high electromagnetic pulse(EMP) sensor using optical-fiber to transmit signal can restrain electromagnetic interference.The Compton electrons scattered by γ-ray irradiated from nuclear explosion or nuclear explosion simulator can generate high EMP,γ-ray can penetrate the shielding box and irradiate the integrated circuit directly.The γ-ray irradiation effect includes interference,latch up and burn out,these will make the measurement result unbelievable.In this paper,the experimental method researching the γ-ray irradiation effect of high electromagnetic pulse sensor on Qiangguang-I accelerator is introduced.The γ-ray dose rate interference threshold is 2×106Gy/s.更多还原
