摘要：
We report output power and frequency measurements of a pulsed free electron laser (FEL) operating as an amplifier at 35 GHz, without guiding field. The experiment used an induction linac, which delivers an 800-A relativistic electron beam (2.2 MeV) with a flat-top of 40 ns into the helical wiggler, The input signal furnished by a 35-GHz magnetron source is amplified to power levels of the order of 80 MW, The experimental results are in good agreement with our simulations, Frequency chirping is observed, and its behavior as a function of the basic FEL parameters is discussed.
