Abstract
Following the recent traveling-wave cyclotron (TWC) amplifier experime nt at MIT, we report in this paper on a frequency modulation (FM) effe ct observed in the TWC oscillator experiment conducted at Tel Aviv Uni versity. 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 bea m spiraling in a metallic periodic waveguide. The TWC oscillator produ ces an RF pulse of approximately 400 W power. Frequency modulation (ch irping) is observed during the TWC pulse by an heterodyne technique. T his effect is related to the electron energy variation during the puls e.
