Model of the steady state corona of a laser plasma, with allowance for deflagration on the critical surface
Abstract
A model of the steady state corona of a laser plasma is developed which assumes the existence of a rarefaction (deflagration) jump that is not related to the effect of light pressure. Due to the anomalously small electron thermal conductivity near the critical point, a hydrodynamic discontinuity (e.g., a temperature or density jump) arises accompanied by nonequilibrium ionization of the ions. The deflagration effect is also manifested in the generation of hard X-rays and of high-energy ions with fluxes of 10 to the 13th to 10 to the 14th W/sq cm. Theoretical results obtained with the model are compared with experimental data.
