Abstract

Physical Sciences Physics Physics, Fluids & Plasmas Physics, Mathematical Science & Technology
This paper applies a time-frequency analysis to the output signal from a coaxial gyrotron oscillator. It is shown that the voltage fluctuations on the diode can be directly correlated to the frequency modulation on the rf output. A simple analytic theory is constructed to explain this correlation. This technique, properly extended, is expected to open up a new way to investigate pulse shortening, mode competition, noise and unwanted frequencies in rf generation. [S1063-651X(98)11211-4].
