Generation of Multi-Color Attosecond X-Ray Radiation Through Modulation Compression

, 2011
In this paper, we propose a scheme to generate tunable multi-color attosecond coherent X-ray radiation for future light source applications. This scheme uses an energy chirped electron beam, a laser modulators, a laser chirper and two bunch compressors ...
