Improved Oscillator Phase Locking Using a Modulated Electron Beam in a Gyrotron.

Abstract

A new method of microwave oscillator phase locking exploiting the extended nature of the gyrokylstron configuration is accomplished by modulating the electron beam before it reaches the cavity oscillator. The amount of power required to phase lock a gyroton is decreased by more than an order of magnitude from that predicted by Alder's theory. In addition, oscillator priming is observed at drive powers below all other systems tested to date. These new methods provide the coherence required of RF sources for linear accelerators and may enhance gyrotron performance for fusion heating. Keywords: Gyrokylstron; Gyrotron; Phase locked oscillator; Primed oscillator.
