ABSTRACT:
An anode assembly of an MHD generator has an opening in communication with the generator's main plasma stream. An inert gas is passed between the anode assembly's emitter and a positively biased collector which is in circuit with a load and a cathode emitter on the other side of the main plasma stream.
A supplemental magnetic field rotates an arc about a collector nozzle in an insulated wall, while a magnetic-field shield protects the assembly from the MHD generator's main flux.
The system is operated by ionizing a gas that is passed between the anode's emitter and its positively biased collector to form a plasma jet which is used as an electrode to conduct current across the main plasma stream between the cathode and the collector of the anode assembly.
