Abstract

Existing ablation models yield acceptable results for thermal plasmas at low and intermediate temperatures. Care should be exercized in extrapolating these results to thermonuclear plasmas because of the limitations inherent in these models: (i) the neglect in the energy transport of the spectrum of stopping lengths or penetration depths corresponding to different energy groups of a single species; (ii) the neglect of the change of the initially spherical expansion of the pellet substance into channel flow along magnetic surfaces and the associated changes in gasdynamic and magnetic shielding; (iii) the neglect of parallel (to the magnetic field) heat conduction effects.
