人工引雷高能辐射观测及数据分析研究

Research on Triggered Lightning Energetic Radiation Observation and Data Analysis

摘要: 本文基于NaI（Tl）探测器搭建了人工引雷高能辐射观测系统。观测到了人工引雷产生的X射线爆发现象，4次成功的人工引雷实验中观测到3次X射线爆发信号。分析发现，人工引雷先导梯级过程的脉冲信号与高能辐射的脉冲信号具有一一对应的特征，表明先导梯级过程可能是闪电高能辐射的产生根源。

Abstract: By using a NaI(Tl) detector, a triggered lightning energetic radiation observation system was set up in this paper. The phenomenon of X-ray bursts produced by triggered lightning was observed, and three X-ray bursts were detected in four successful triggered lightning tests. The analysis result shows that the stepped leader signals of the triggered lightning have a one-to-one correspondence with the energetic radiation signals, and this indicates that the stepped leader may be the source of lightning energetic radiation.
