KLYSTRON OSCILLATOR USING COLD CATHODE ELECTRON GUN, AND OSCILLATION METHOD

摘要

Disclosed is a cold cathode klystron oscillator and the oscillation method thereof. The cold cathode klystron oscillator according to the present invention comprises an electron source by a cold cathode that emits a primary electron; a first grid that focuses and accelerates an electron beam emitted in the electron source; a second grid that focuses and accelerates the electron beam passing through the first grid, and includes a resonator that converts a part of the mechanical energy of the electron beam passing through the first grid into an electromagnetic wave energy; and a secondary electron cold cathode that generates a secondary electron by colliding the electron beam passing through the second grid. Here, the focusing and the acceleration of the electron beam passing through the first grid and the second grid are made through a DC power supply.
