Study of material destruction during powerful plasma exposure.

Results of experimental research during the interaction of powerful plasma flow with aluminum and graphite targets are presented. The experiments were carried out at plasma energy density of up to 5 MJ/m{sup 2} and time duration of up to 600 {micro}s. Strong damage of target materials was observed as a result of the plasma flow interaction as well as the formation and the ejection of macroscopic particles from the target surface. The ejected particle size and spatial distribution were measured as well as the velocity of these particles during the experiments. The method of laser scattering was applied for these measurements.
