F. Ciocci et al., ANALYSIS OF THE OPTICAL-KLYSTRON GAIN DEPRESSION INDUCED BY INHOMOGENEOUS BROADENING EFFECTS, Optics communications, 103(3-4), 1993, pp. 307-314
The modification induced in the Optical-Klystron gain by an e-beam wit
h non-negligible energy spread and emittances is analyzed. The analysi
s is carried out including the inhomogeneous broadening contributions
due to the undulators and dispersive parts. The paper deals essentiall
y with the low gain regime, the corrections due to the high gain effec
ts are also discussed.
