Techniques for the Simulation of the Space Plasma Environment,

Abstract

The effects of space plasmas with distributed spectra of particle energies can be simulated in the laboratory by combinations of monoenergetic electron and ion beams. The energy and current density of beams are calculated to match various moments of the velocity distribution function of distributed spectra. Analytical solutions have been found for one- and two-beam matching, respectively, of two- and four-velocity moments of arbitrary distribution functions. A three-energy solution which matches six moments of a Maxwellian distribution is presented, as well as multiple-beam solutions for matching two-Maxwellian distributions. (Author)
