| Outline of Final Research Achievements |
We performed a study on polarized x-ray generation based on self-seeding inverse Compton scattering at Research Center for Electron Photon Science (ELPH), Tohoku University. In this study, we were able to demonstrate experimentally about two important issues that one is an extremely short electron bunch generation and another one is the generation of coherent undulator radiation. The pulse length of short electron bunch was measured using Michelson interferometer, and the deduced bunch length from frequency spectrum of the radiation was approximately 80 fs (rms). The coherent undulator radiation in terahertz region was successfully observed and its characteristics were measured. The results obtained from these experiments are valuable information for the research field related to beam physics and high intensity radiation generation.
