Abstract

The spectral-angular characteristics of the electromagnetic radiation produced during the propagation of fast charged particles through an absorbing medium with finite dimensions are considered using equations of macroscopic electrodynamics. The change in its angular distribution is studied after achievement of the Vavilov–Cherenkov radiation threshold. The yield of the transition radiation produced at high particle energies and the spectral characteristics of the Vavilov–Cherenkov radiation in the X-ray frequency range are analyzed.

有限尺寸吸收介质中的X射线Cherenkov辐射

摘要

使用宏观电动力学方程，可以考虑快速带电粒子通过有限尺寸的吸收介质传播过程中产生的电磁辐射的光谱角度特性。在达到Vavilov–Cherenkov辐射阈值后，研究其角度分布的变化。分析了在高粒子能量下产生的过渡辐射的产量，以及在X射线频率范围内Vavilov–Cherenkov辐射的光谱特征。
