Abstract

The flux transport effect on the radiation-induced plasma density profile and ablative flow outside the resonance layer in steady state in one dimensional spherical geometry studied. The numerical predictions conclude the existence of plateau-like plasma density profile rather than overdense bump formation in the underdense plasma. The plasma density profile, though retaining its shape, becomes more pronounced as the heat flux is increased. However, the length of the plasma density plateau is found to be quite small when compared with the isothermal case.
