Abstract

The authors have considered the charging of spherical particles in a plasma, taking into account the electric field emission of electrons from the dust particles and the change in the electron/ion densities in the plasma. The dependence of the charge of a particle and electron/ion densities on the radius and number of dust particles and the density of electrons/ions and the temperature in the undisturbed plasma has been studied numerically without and with the inclusion of the electric field emission of electrons from the particles. It is seen that both the electric field emission and the electron/ion kinetics significantly affect the charging process.
