Abstract

We present a unified linear analysis which describes free electron lasers based on Cerenkov and Smith-Purcell effects and T.W. amplifiers. In the single electron interaction regime the analysis reproduces the exponential and non exponential (interferential) gain expressions. It is shown that the first expression is dominant and that considerable increase in the gain can be attained by using electron beams with small velocity spread.
