Abstract
An electron gun that generate an electron flow and the application of this gun to produce rf energy or for injectors. The electron gun includes an electrostatic cavity having a first stage with emitting faces and multiple stages with emitting sections. The gun also includes a mechanism for producing an electrostatic force which encompasses the emitting faces and the multiple emitting sections so electrons are directed from the emitting faces toward the emitting sections to contact the emitting sections and generate additional electrons and to further contact other emitting sections to generate additional electrons and so on then finally to escape the end of the cavity. A method for producing a flow of electrons.
Claims8
A method for producing electrons comprising the steps of:
- moving along at least a first electron in a first direction from a first location;
- striking a solid first area with the first electron where the first electron terminates;
- producing additional electrons moving along the first direction through a transmission mode at the first area due to the first electron striking the first area on the opposite side of the first area which was struck by the first electron;
- moving along the additional electrons in the first direction from the first area to a solid second area;
- striking the second area with the additional electrons;
- and
- creating more electrons moving along the first direction on the opposite side of the second area due to the additional electrons from the first area striking the second area.
An electron gun comprising:
- an electrostatic cavity having a first stage with multiple electron emitting faces and multiple stages with solid electron emitting sections from which electrons are emitted in a first direction;
- and
- a mechanism for producing an electrostatic force that acts on the multiple electron emitting faces and the respective multiple electron emitting sections so electrons moving in a first direction from the respective multiple electron emitting faces and sections are directed in the first direction from the multiple electron emitting faces toward the respective multiple emitting sections to contact the respective solid multiple emitting sections and terminate in the respective emitting sections and generate additional electrons on the opposite side of the respective multiple emitting section in a transmission mode moving in the first direction and to further contact other emitting sections.
