Abstract

Ground-based observations of cosmic rays by the spectrographic global survey method were used to study the ground-level enhancement in cosmic ray intensity on August 24, 2002. Spectra of variations of primary cosmic rays and their anisotropy were obtained. Based on measurements from the GOES spacecraft and global network of cosmic ray stations, the differential rigidity spectra of accelerated particles in the vicinity of the Sun were calculated. The maximum rigidity to which solar particles were accelerated was estimated.

GLE64 期间宇宙射线的光谱和各向异性

摘要利用光谱全球巡天法对宇宙射线进行了地基观测，以研究 2002 年 8 月 24 日宇宙射线强度的地面增强。获得了初级宇宙射线的变化谱线及其各向异性。根据 GOES 航天器和全球宇宙射线站网络的测量结果，计算了太阳附近加速粒子的差异刚度谱。估计了太阳粒子被加速到的最大刚度。
