Screening of a flow of evaporated metal atoms by the Langmuir layer formed at the point of contact of hot plasma with metal

Resumo

We have theoretically analyzed conditions under which the screening of a flow of evaporated metal atoms by the Langmuir layer formed due to ionization of atoms in this layer can significantly influence the dynamics of hot plasma in contact with a metal surface. It is established that allowance for the screening of evaporated atomic flow by this Langmuir layer is necessary in many cases, in particular, in simulations of laser-plume dynamics.
