Transition from unstable electrostatic confinement to stable magnetic confinement in a helicon reactor operating with Ar∕SF₆ gas mixtures
Two types of instabilities were previously identified in inductive discharges having an expanding chamber when negative ions are present: (i) the sourceinstability, occurring in the neighborhood of the capacitive-to-inductive (E to H) transition, and (ii) the downstream instability, which was shown to be the periodic formation and propagation of double layers. These unstable double layers were found over the entire parameter space (pressure/power) of interest, and they were born at the...[Show more]
