In earlier works the Krook model for nonlocal electron energy transport in laser produced plasmas was examined. This paper extends the earlier work by treating spherical configurations, specifically laser driven implosions. Additions to the theory due to spherical geometry are worked out. As in the planar case, the nonlocal effects manifest themselves both as flux limitation and preheat. Nonlocal transport does have an effect on the fusion gain of laser pellet implosions.

    To increase the power level of the sources of coherent electromagnetic radiation at frequencies from 100 GHz up to the terahertz range it makes sense to develop devices with a spatially extended interaction space. Sheet-beam and multiple-beam devices belong to the category. In the present paper...
