Transient conduction electrons in irradiated insulators

The authors performed calculations of transient conduction electron populations and electrical conductivities induced by irradiation of insulating solids. Production of secondary electrons, their energy exchange with the medium, and their eventual capture or recombination are included. The results are of particular interest in connection with the propagation of intense relativistic electron beams in solids, and the radiation response of solid state devices, but may have a wider application. A goal has been to determine the form of the dependences upon radiation intensity, to enable the extrapolation of experimental results to higher intensities. Calculations showing several distinct regimes of intensity dependence are presented
