Abstract

The research results of an opportunity of radiation-stimulated diffusion use for laser fusion microtargets filling with heavy gases are given, which they can not be filled with by means of usual diffusion. The theoretical estimates of quantity and character of radiation damages, their distribution in the volume of an irradiated material are made. The calculations of glass microshells argon filling process in mode of vacancy and effusive mechanisms of wall permeability are carried out. The experiments on argon filling of glass microspheres are carried out by means of diffusion with irradiation of them with electrons, protons and neutrons. It is experimentally shown that the neutron irradiation of the glass microspheres placed in the chamber with argon in the reactor IBR-2 (JINR, Dubna) and their subsequent annealing has resulted in the argon penetration into microspheres.
