Title:
GYROTRON OSCILLATOR OF MULTIBORE CAVITY FOR REDUCING MODE BYCOMPETITION
Document Type and Number:
Japanese Patent JPS59114730
Kind Code:
A
Abstract:
In a gyro-monotron oscillator a single, "monotron" cavity is used to interact with the electron beam. To handle very high powers without excessive cavity loss, the cavity is excited in a higher order mode such as TE0m1. Other modes can be resonant in the cavity, interfering with the operation when their frequency is near the operating frequency. To increase the mode separation, an upstream section of the cavity is made smaller, to support only a lower-order mode such as TE011. Also, the beam is pre-bunched by this lower order, interference-free mode so has less tendency to interact with spurious modes in the higher order cavity.
