DEPENDENCE OF THE RADIAL PROFILES OF THE PLASMA PARTICLES DENSITIES ON THE AFTERGLOW TIME IN THE FLOWING AFTERGLOW PLASMA

The simultaneous radial and axial decay in the flowing afterglow plasm a has been investigated for metastable atoms, atomic and molecular ion s and electrons. The exact solution of this problem leads to a set of differential equations. The stability of the numerical solution of the se equations is not clear. The aim of the present paper is to simplify the mathematical description of the problem and to solve it on the ba sis of experimental results obtained in the argon flowing afterglow in itiated by a microwave discharge.
