The development and improvement of methods for measuring and detecting lightning discharge phenomena in orbital and laboratory experiments was carried out. Laboratory modeling of lightning discharge was carried out jointly with the Institute of Applied Physics of the Russian Academy of Sciences by studying the parameters of electromagnetic radiation of high-voltage discharges at the Groza GIN-1MV facility. In this case, electromagnetic radiation of high-voltage discharges generated at the Groza GIN-1MV facility was detected using detectors-spectrometers developed by the Scientific Research Institute of Nuclear Physics of Moscow State University for X-rays and gamma rays (with photon energy over 10 keV).
Mareev et al. (Mon,) studied this question.
