Abstract
The JAERI FEL linac is energized with four kinds of all-solid-state am plifiers having 5, 1.5, 4, and 50 kW of peak power with a 1-2 ms pulse length. Amplitude and phase stabilities of the 50 kW amplifiers are a pproximately 1% and approximately 1-degrees, respectively. A feed-forw ard loop circuit is effective when a feedback loop circuit is not able to stabilize the output of rf power.
