This paper presents methods of detection and spectrometry of high-energy electrons and positrons produced in the interaction of laser radiation with matter and vacuum. The methods are based on charged particle transport in the magnetic field of a hollow coaxial line through which a direct current flows. The methods make it possible to detect particles at a distance of several dozen meters from the source with retention of close to 100 % collection efficiency and provide efficient detector protection from background radiation.

基于同轴线磁场传输的超强电磁场中产生的带电粒子的检测和光谱测定方法

本文介绍了检测和光谱法在高能电子和正电子的相互作用中产生的激光辐射与物质和真空的相互作用。该方法基于带电粒子在空心同轴线的磁场中的传输，直流电通过该空心线传输。该方法可以在距源数十米的距离处检测粒子，并保持接近100％的收集效率，并为背景辐射提供有效的检测器保护。
