HARD PHOTONS POWERFUL RADIATION OF ELECTRON BUNCH INTERACTING WITH PLASMA BEAT WAVES

摘要

Radiation process of electron bunch moving towards plasma beat waves is investigated. The plasma beat waves are excited by two laser pulses with difference of frequencies coinciding with plasma frequency. Then a strong longitudinally periodic electric field is generated. This brings to the longitudinal oscillations of bunch electrons with plasma frequency. As a result a powerful so called "hybrid radiation" is generated with combined properties of transition radiation and undulator radiation.
