N2 - Following the recent traveling-wave cyclotron (TWC) amplifier experiment at MIT, we report in this paper on a frequency modulation (FM) effect observed in the TWC oscillator experiment conducted at Tel Aviv University. The TWC oscillator operates in the microwave regime (9.4 GHz). It consists of a low-energy (8 keV) low-current (0.2 A) electron beam spiraling in a metallic periodic waveguide. The TWC oscillator produces an RF pulse of t 400 W power. Frequency modulation (chirping) is observed during the TWC pulse by an heterodyne technique. This effect is related to the electron energy variation during the pulse.
