Title:
【発明の名称】マイクロ波エネルギー発生装置
Document Type and Number:
Japanese Patent JP3067723
Kind Code:
B2
Abstract:
An apparatus for generating a microwave frequency energy includes a cathode for emitting electrons, a first grid for controlling and focusing the flow of electrons from the cathode, a choke structure for serving as a capacitor, wherein the cathode, the first grid and the choke structure define an input cavity functioning as a resonant circuit. The apparatus further includes a trimming resistor, one end of which is connected to the first grid and the other end thereof is connected the cathode, for inducing a bias voltage on the first grid, a second grid provided above the first grid and having a plurality of slots through which the electron beams passing through the slots of the first grid pass, an anode for receiving the electrons passing through the slots of the second grid, a driving voltage source for providing a driving voltage to the cathode and the anode, an antenna for extracting the microwave from an output cavity, the output cavity being defined by the second grid and the anode , and a feedback structure extending from the input cavity to the output cavity, for feeding a portion of the microwave frequency energy back to the input cavity.
