| Outline of Final Research Achievements |
Free-electron laser coverts kinetic energy of a high energy electron beam to laser light though its conversion efficiency is not high. High intensity coherent radiation is generated in a wavelength region around the bunch length of an electron beam when it is bent in a magnetic field, but the bunch length is not shorter than 1 mm. This study aimed to develop a new method for generation of high-intensity monochromatic coherent light using free electron laser as a short electron bunch generator. The energy profile of the electron beam was measured for the free-electron laser in operation and it turned out the energy spread was larger than expected. Micro-bunches generated in the free-electron laser are considered to be smoothed out in a uniform magnetic field, so that it is necessary to adopt a special magnetic field to maintain the bunching.
