Abstract: 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.

Keywords: positron, detector, time-of-flight magnetic spectrometer.
