Simulations of the Relativistic Runaway Electron Av Avalanches lanches (RREA) in the thunderclouds above the Aragats space Env Environmental ronmental center (ASEC)

摘要

GEANT4 simulations of t the Relativistic Runaway Electron Avalanches(RREA) were performed he In this pa paper to explain the Terrestrial Ground Enhancements(TGEs) detected by the particle detectors of Aragats Space E per En- nvironmental Center(ASEC) operated at altitude 3200m on slopes of mt. A vironmental Aragats, in Armenia. The RREA was sim ragats, simu- ulated in the uniform electric fields of different strengths. The gamma ray, electron and neutron energy spectra were lated obtained at different altitudes, thundercloud and beneath. Experimental data are compared with the res results of simul ults simula- ations. tions.
