Abstract 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.

雷暴中的同位素产生

摘要 雷暴和闪电是自然的粒子加速器系统。由相对论失控电子雪崩引起的地面伽马射线闪光会产生 X 射线和 γ 射线爆发,其能量足以在大气中产生光核反应。这种反应会产生新的同位素,从而局部改变空气成分,并产生检测和表征这种高能现象的新方法。在这项工作中,我们使用通用蒙特卡洛传输代码 FLUKA 探索了地球伽马射线闪光后次级物质的产生,并详细分析了新同位素的产生。研究了它们的丰度、时间和能量分布,这对建立新的测量策略很有用。
