Paper Abstract

The paper concentrates on possible applications of plasmas to FELs and closely related radiation sources. The possibility of using intense longitudinal plasma oscillations as wigglers for FELs is assessed, and three methods of generating intense plasma waves are presented: one utilizes two intense laser beams of different frequencies, the other employs shining a laser on a plasma with a resonance layer, and the third uses the wake fields of charged bunches from a linear accelerator. It is also demonstrated that by using plasma beat-wave or plasma wake-field accelerators, bunches as short as a few microns can be produced. The possibility of matching the group velocity of the EM wave to the electron velocity is considered, and cyclotron autoresonance masers and ion-channel lasers are covered.
