Research Activities on a MIR-FEL and Table-Top THz Generation in Kyoto University
H. Ohgaki,T. Kii,K. Masuda,M. A. Bakr,K. Higashimura,R. Kinjo,S. Ueda,T. Sonobe,Y. U. Jeong,K. Yoshida 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.21
Free Electron Lasers (FEL), which could be useful for developing energy materials, have been exploited at the Institute of Advanced Energy, Kyoto University. A mid-infrared FEL has been developed, and FEL gain saturation at 13.2 µm was achieved for the first time in May 2008. A FEL beam characterization was performed. A macro pulse energy of 5 mJ/pulse and a peak power of about 3 MW were achieved. A FEL beam transport system was constructed in the user room. Furthermore a tabletop THz FEL amplifier for the spectral range from 150 to 300 µm, which consists of a photocathode RF gun and an undulator, has been proposed to strengthen the materials research. For evaluation of the proposed design, a start-to-end simulation was carried out. An output power of about 350 kW is expected with the proposed system.
