Fundamental parameters of laser and X-ray interaction with matter are cruci
al in high energy density physics research. ISKRA-5 laser is used for exper
imental investigation of X-ray transport in various targets, Cylindrical ch
annels investigated on ISKRA-5 are simulated using diffusion-vacuum and kin
etic approximations. The effects of 3D target geometry and kinetic characte
r of X-ray transport are discussed. (C) 2001 Published by Elsevier Science
