Assessment of a Novel RF LINAC Amplifier Concept
Abstract
In this report, we discuss a potential method of increasing the peak current of an rf linear accelerator without significantly degrading the transverse emittance of the beam. This can be achieved at the expense of increasing the longitudinal phase space of the beam; if this increase in longitudinal phase space is acceptable, the Free Electron Laser performance does not degrade much. First, we describe our concept for increasing the micropulse peak current. We then estimate the change in brightness of the beam using first order transport properties of the beam. We have also analyzed the performance of the FEL amplifier for different electron and optical beam parameters using a one-dimensional code. The advantages of increasing the peak current are clearly shown. Finally, we present the results of our analysis on the transient stimulated Raman scattering analysis and its effect on both up and down links. Keywords: Electron beams, Laser amplifiers.
