论文摘要
相对论的失控电子雪崩(RREA)在电云中产生的产生伽马辐射,可以在地面和近地轨道上观察到。 RREA的无线电发射是雪崩过程中研究得多的表现。同时,VHF辐射可以用作有关RREA开发条件的其他信息来源。 我们提出了使用geant4蒙特卡洛模拟来计算rreas产生的VHF信号的方法。我们表明,失控电子产生的VHF辐射在频率范围为0.1--1 MHz时,幅度低于背景噪声。
Relativistic runaway electron avalanches (RREAs) developing in electrified clouds produce gamma radiation which could be observed both on the ground surface and on near-Earth orbit. Radio emission of RREAs is a much less studied manifestation of the avalanche process. Meanwhile, VHF-radiation can be used as an additional source of information on conditions of the RREA development. We present the method of calculating the VHF signal produced by RREAs using Monte-Carlo simulation with GEANT4. We show that VHF radiation produced by runaway electrons has a maximum at frequency range 0.1--1 MHz, the amplitude is below the background noise.
