Abstract
A multipactor discharge tuned resonant cavity device, e.g. a magnetron, is arranged with two multipactor discharge electrodes so that in a discharge condition a net current flows from one electrode to the other. The net current is used to create a self-bias voltage on one of the electrodes which affects the operating frequency of the device.
Claims13
A multipactor discharge arrangement comprising a source of radio frequency energy, two multipactor discharge electrodes arranged such that one surrounds the other to form a co-axial waveguide which is coupled to said source of radio frequency energy whereby, in operation, in a multipactor discharge condition a net current flows from one of said multipactor discharge electrodes to the other, and means connected to utilize such net current to create a self-bias voltage on one of the electrodes.
A multipactor discharge arrangement comprising, in combination:
- a source of rf energy;
- coaxial waveguide means coupled to said source for receiving rf energy therefrom in which a radial electric field is present;
- and
- a multipactor discharge device forming part of said coaxial waveguide means, said device comprising an inner electrode and an outer electrode surrounding said inner electrode whereby in response to multipactor discharge between said electrodes a net current of electrons flows to said outer electrode and resistor means connected between said inner and outer electrodes for creating a self-bias voltage on said outer electrode across said resistor means due to said net current.
A multipactor discharge arrangement comprising, in combination:
- a resonant cavity device;
- coaxial waveguide means coupled to said resonant cavity device and including an inner conductor extending into said device and an outer conductor;
- and
- multipactor discharge means forming part of said coaxial waveguide means for affecting the operating frequency of said device during multipactor discharge, said multipactor discharge means comprising an inner electrode connected to said inner conductor and an outer electrode connected to said outer conductor and surrounding said inner electrode whereby a net electron current flows to said outer electrode during multipactor discharge, and reactance means connected between said inner and outer electrodes for creating a self-bias voltage on said outer electrode during multipactor discharge.
