Abstract

The electron distribution fonction in a particle-beam generated plasma is derived in its low- and medium-energy portion (under the first excitation threshold) from a Boltzmann equation, which contains elastic and inelastic collisional processes and a continuous source term. This equation is analytically solved and we discuss the importance of the non-Maxwellian deviations and their consequences for the determination of macroscopic values such as electron density or ‘temperature’. A numerical discussion is included for the case of an argon plasma created by a high-energy electron beam between 103 and 106 eV.
