| Outline of Final Research Achievements |
This work aims at demonstrating a Smith-Purcell free electron laser (FEL) at evanescent wavelength for a high power compact radiation source at THz wavelength. The compact THz source consists of an electron gun and a grating for Smith Purcell radiation. We successfully delivered 4.3 mA beam at 150 kV which will satisfy electron beam performance necessary for FEL amplification and prepared a vacuum chamber consisting of a grating on a linear motion and a THz diode detector with a focusing horn and a mesh filter with 10% band width. We however encountered a vacuum trouble where the gun system was exposed to 1 Pa air. We could not recover every system within limited time schedule. We will continue our Smith-Purcell FEL experiment.
