abstract = {We report on a transport model for the Lyman line radiation
in optically thick divertor plasma conditions encountered in
exhaust systems in magnetic fusion devices. The model is
designed to switch automatically between a kinetic and a
continuum description according to the plasma conditions and
to the spectral range. A kinetic treatment is retained for
photons with a large mean free path (line wings), whereas a
continuum description of the radiation field is invoked in
highly absorbing or scattering regions (core photons).
Prototypical calculations of this so-called δf Monte Carlo
type of the Lyman α photo-excitation rate in slab geometry
are performed as an illustration. The hybrid method is
suggested as a candidate for speeding up the kinetic
transport codes currently involved in magnetic fusion
research for ITER and DEMO divertor (power and particle
exhaust system) design.},
