Abstract
A high temperature plasma generating system has a ceramic magnetron insulator joined to a frustoconical waveguide reflector. A cavity magnetron tube is joined to the frustoconical waveguide reflector. An antenna is set in the cavity magnetron tube and extending through the ceramic magnetron insulator. Applying an electrical current to the magnetron creates multipactor in the frustoconical waveguide reflector generating plasma focused at the tip of the magnetron antenna.
Claims20
A system configured to create generate plasma;
- the system comprising:
- a ceramic magnetron insulator, joined to a frustoconical waveguide reflector;
- a cavity magnetron tube, joined to the frustoconical waveguide reflector;
- and
- an antenna, set in the cavity magnetron tube and extending through the ceramic magnetron insulator;
- wherein applying an electrical current to the cavity magnetron creates multipactor in the frustoconical waveguide reflector generating plasma within the frustoconical waveguide reflector and creating a focused plasma.
