      A spectral model of fast electron transport accounting self-consistent electric fields is described. The model is implemented within the ZARYA package intended for computing target implosion by laser radiation. A numerical method for solving fast electron transport equation is presented. Computational results are given to illustrate the importance of accounting fast electron scattering, self-consistent electric fields, inverse current effects along with the possibility to interpret experiments on gas-filled shells both using a compressed target portion (compression level, neutron yield) and fast ions formation resulting from an acceleration by self- -consistent electric fields.
