Electrostatically driven plasma hydrodynamic instability. 1: The failure of vacuum-insulated, long wavelength laser fusion pellets
Abstract
Longer wavelength laser radiation generates relatively large fluxes of superthermal electrons that penetrate and preheat the cores of such pellets at early times in their implosion history, precluding their efficient subsequent compression. Separation of the outermost shell of such pellets from its inner regions by a vacuum layer is considered analytically and computationally. Results of such considerations are presented. The results developed also apply to a variety of formally similar phenomena, ranging from the relativistic edge of supernova photospheres to diode breakdown in REB machines.
