Abstract

An axisymmetric model is used to study changes in the shape of the Earth’s radiation belts and energy spectra of charged particles in them during a geomagnetic field reversal. Regions of stable existence of radiation belts are obtained analytically by generalizing the Størmer theory to the case of an axisymmetric quadrupole. An reversal scenario is proposed in which it is shown that a gradual reduction of radiation belts can occur with a decrease in the dipole component of the modern geomagnetic field. The spatial and energy distributions of the flux density of protons and electrons are obtained, which made it possible to determine the maximum dose rate of radiation on various magnetic shells during the reversal process.

磁场反转期间的辐射带

摘要

轴对称模型用于研究地磁场反转期间地球辐射带的形状变化以及其中的带电粒子的能谱。通过将Størmer理论推广到轴对称四极杆的情况，可以得到辐射带稳定存在的区域。提出了一种逆向方案，其中表明随着现代地磁场的偶极子分量的减小，辐射带会逐渐减小。获得了质子和电子通量密度的空间和能量分布，这使得有可能确定在反转过程中各种磁性壳上的最大辐射剂量率。
