HEATING AND ENHANCED DIFFUSION DURING A BEAM-PLASMA INSTABILITY,
Abstract
An enhanced plasma diffusion is observed during the interaction of an electron beam of 0.1-1amp. current with a weakly ionized Ne-afterglow plasma. The parameter dependence of this effect is investigated in the electron density region 10 to the 10th to 13th power electrons/cc and the pressure range 0.01-0.1 Torr. Evidence is presented that this diffusion is due to heating of the plasma electrons partly by collisional damping of unstable plasma waves and partly by thermalization of secondary electrons emitted in ionizing collisions between beam electrons and neutral neon atoms.
