Weakly Ionized Plasma

Upgraded method of determining basic parameters of weakly ionized plasma by means of photometric study of bremsstrahlung emission continuum in visible spectrum range is described. Time-averaged spatial distributions of electron temperature and density in planar plasma jet formed by capacitive RF discharge in atmosphere pressure argon at the discharge glow in a low-current α-mode are experimentally obtained.

Weakly Ionized Plasma

Diagnostic studies were made on a supersonic (Mach 2.5) weakly ionized plasma jet in argon. Electrical probe techniques were used in conjunction with spectroscopic and photographic methods. The results indicate a fairly uniform axial behavior of temperature, but the radial profiles show considerable variation. Temperature measurements made by different methods disagree sufficiently to show a probable lack of equilibrium between translational, rotational, vibrational, and electronic excitation energy modes.

Weakly Ionized Plasma

The properties of certain wave modes excited in a weakly ionized plasma placed in an external d.c. electric field are analyzed from the standpoint of the linearized kinetic equation, the electron steady-state distribution function being taken in the form of the extended Margenau–Davydov and, in particular, Druyvesteinian. The presence of absolute stability cones formed by certain propagation directions is found. The corresponding critical values of the electron drift, destabilizing each of the modes considered, is also evaluated for a plasma with a Druyvesteinian distribution.
