Microwave heating of electrons and stability of a weakly ionized plasma in a magnetic field
It is shown experimentally that an increase in electron temperature produces a gradual stabilization of the afterglow of a weakly ionized plasma in a homogeneous magnetic field. Increasing T/sube//T/subi/ reduces the fluctuations in the plasma potential and density. For Teapproximately-greater-than (2-4) center-dot10$sup 3$ degreeK, the relative amplitudes are smaller than 10$sup -2$- 10$sup -3$ over the entire range of densities and magnetic fields that have been studied. The transverse diffusion coefficient is classical under these conditions. The experimental results are in qualitative agreement with theoretical ideas on the stability of a plasma against small-scale, drift instabilities, in which neutrality can be violated.
