Calculation of thermonuclear particle spectra and yields by the Monte Carlo method in the present experiments on laser fusion

The Monte-Carlo method is used for calculating the distribution functions of charged and neutral thermonuclear particles, the products of thermonuclear reactions in an inhomogeneous confined laser plasma. The results of calculations of space distribUtion of the thermonuclear particle energy release in plasma, and also the spectra and yields of particles escaping its limits, carried out in the conditions of present experiments on laser irradiation of targets in the ''Kal'mar'' and ''Argus'' devices are presented. The calculations by the ''TERA'' program show that different space temperature and density distributions of laser plasma realized in the ''Kal'mar'' and ''Argus'' experiments form different pictures of kinetics of thermonuclear particles in this plasma. Under the ''Kal'mar'' experiment conditions such a high density of a target shell is achieVed that α-particles do not escape its limits at all. For the ''Argus'' experiment the calculation spectrum of α-particles is in a good agreement with the measured one
