论文摘要
雷暴和闪电是天然粒子加速器系统。由相对论失控的电子雪崩引起的陆地伽马射线闪光，产生$ x $和$γ$射线的爆发，足以在大气中产生照片核反应。这种反应会导致新的同位素的产生，从而在局部修改空气组成，并产生新的方法来检测和表征这种高能现象。在这项工作中，我们使用通用蒙特卡洛运输代码Fluka进行探索，在陆地伽马射线闪光灯闪光后生产次要的生产，并详细分析了新的同位素的产生。研究了它们的丰度，时间和能量概况，这对于建立新的测量策略可能很有用。
Thunderstorms and lightnings are natural particle accelerator systems. Terrestrial gamma-ray flashes, caused by relativistic runaway electron avalanches, produce bursts of $X$ and $γ$ rays, energetic enough to produce photo-nuclear reactions within the atmosphere. Such reactions cause the generation of new isotopes, which modify the air composition locally and produce new ways of detecting and characterizing this high-energy phenomena. In this work we explore, using the general purpose Monte Carlo transport code FLUKA, the production of secondaries after a Terrestrial gamma-ray flash and analyze the generation of new isotopes in detail. Their abundance, time and energy profiles are studied, which can be useful for establishing new measuring strategies.
