Parametric study of dissipative drift modes and their dynamic stabilization in a weakly ionized plasma

Abstract
A detailed experimental study is made of dissipative drift modes in a weakly ionized plasma. The appearance of various modes as the plasma parameters are changed is compared with theory. A detailed study of the m = 3 mode in cylindrical geometry shows good agreement between experiment and a locally applied theoretical model. A method of dynamic stabilization using oscillating azimuthal magnetic field is studied and theory and experiment are compared for the m = 3 mode.
