摘要：

Development of Chemical Oxygen-Iodine Lass (COIL) in Tokai University is described. From FY1996, we have conducted a three-year research project sponsored by NEDO (New Energy and industrial technology Development Organization), and it was finished in March 1999. As a result, high-efficiency operation (23.4%) of COIL with nitrogen as a buffer gas was demonstrated. Reduction of the vacuum pump size by the high-pressure subsonic mode operation with turbo blower was demonstrated. Specific energy reached to 3.5J/liter. Output power stabilization/modulation technique by the external magnetic field was developed. Twisted Aerosol Singlet Oxygen Generator (TA-SOG) was tested and its performance was compared to liquid-jet SOG. TA-SOG was operated at the internal gas velocity of 85 m/s. Novel unstable resonator was developed with the aid of newly developed FFT code. We are now conducting a one-year project whose goal is a development of a 1kW-class system capable of one-hour stable operation. Finally, three operation modes of future industrial COIL are proposed.
