Generation of secondary electrons from the interaction of high-energy beams with the upper atmosphere

Summary form only given. The injection of beams of neutral and plasma bunches into the atmosphere and magnetosphere is at present an active and fruitful method of researching geophysical phenomena. Such studies have relevance to the functioning of space vehicles (SVs), whose operations are in many respects governed by their resistance to flows of charged particles and electromagnetic fields. Therefore, an urgent problem is the evaluation of the effects of particles and fields on SVs. The authors have developed a numerical model based on "large particles", which allows the description of the occurrence and transport of high-energy, low-density electron beams resulting from active experiments in the atmosphere.
