Outline of Final Research Achievements

The temporally modulated electron bunch is useful for applications employing coherent phenomena of electron beam such as FEL (Free Electron Laser), coherent radiation, drive beam for the dielectric accelerator, etc. In this project, the temporally modulated bunch (micro-bunch structure) generation with the spatial modulation and the phase-space rotation was studied. According to the result, it is confirmed that the micro-bunch structure can be generated by this method with a large operability. It can be applicable for the pre-bunched FEL and potentially for the drive beam of the di-electric optical accelerator.
