Abstract
The Free Electron Laser (FEL) dynamics is characterized by the interplay between banching and emission processes. The first mechanism can be quantitatively specified in terms of the so called bunching coefficients, which determine the degree of the bunching at fundamental and so higher harmonics. Numerically the Lionville equation is solved, ruling the longitudinal FEL phase-space dynamics, and evaluate the bunching coefficients. The dependence of these coefficients on various parameters is analized, like the e-beam energy spread, the laser intensity ect. The simple scaling formulae and the usefulness of the results for the design of FEL exploiting prebunched e-beams are presented and discussed.
