摘要: Abstract A self-consistent approach based on the simultaneous solution of vibrational master equation, Boltzmann equation and plasma chemistry describing dissociation process has been used to obtain: (a) distributions, (b) electron energy distribution functions, (c) number densities ( n c ) temperatures T ), (d) degree dissociation, (e) concentration negative ions N H − in magnetic multicusp 2 plasmas. The is an extension a model presented earlier. main differences come from insertion source term (an beam) instead electric field inclusion new important processes equation. results which are satisfactory agreement with experimental distributions obtained by CARS spectroscopy, , values probe techniques production photodetachment technique, show importance hydrogen atoms wall deactivation affecting properties
