磁层中宇宙射线的色散和聚焦
Dispersion and focusing of cosmic rays in magnetospheres
摘要:
要模拟宇宙射线粒子对行星大气的照射,除其他外,需要能够理解和量化带电粒子与行星磁场的相互作用。在这里,我们提出了一个过程,这是经常被忽视的研究;分散和磁层中的宇宙射线轨迹的聚焦。计算是使用我们的新代码CosmicTransmutation进行的,该代码是为研究流星体和行星大气中宇宙成因核素的产生而开发的,其中包括计算大气层顶部的辐照光谱。在这里,我们讨论的影响所造成的分散和集中的宇宙射线粒子轨迹。
英文摘要:
Simulating the irradiation of planetary atmospheres by cosmic ray particles requires, among others, the ability to understand and to quantify the interactions of charged particles with planetary magnetic fields. Here we present a process that is very often ignored in such studies; the dispersion and focusing of cosmic ray trajectories in magnetospheres. The calculations were performed using our new code CosmicTransmutation, which has been developed to study cosmogenic nuclide production in meteoroids and planetary atmospheres and which includes the computation of the irradiation spectrum on top of the atmosphere. Here we discuss effects caused by dispersion and focusing of cosmic ray particle trajectories.
