Increase in effective hall parameter of a nonequilibrium plasma by applying a secondary high-frequency discharge
Numerous experimental and theoretical investigations have shown that a nonequilibrium current-carrying plasma is unstable in a transverse magnetic field, and the effective Hall parameter measured in it ..beta..*=E/subH//E/subj/ (E/subj/ is the field along the current, and E/subH/ is the Hall field) is usually saturated at a level of 1-2. To damp the ionization instability and increase the Hall parameter, a current has been passed through a plasma in a direction parallel to the magnetic field; this method of increasing ..beta..*, however, is disadvantageous from the energy standpoint since the stabilized current should exceed the current transverse to the magnetic field by a factor of root..beta..*. In the present paper ..beta..* is increased by applying a secondary low-power hf discharge to an independent quasistationary discharge. (AIP)
