Several modifications have been made for the JAERI Free Electron Laser (FEL) system in order to extract greater average lasing power. The electron gun was improved to produce an electron beam with 1 ns pulse width, 600 mA peak current, amplitude fluctuation less than 1% and timing jitter less than 0.1 ns. In addition, the 180° bending are was modified to match the beam envelope inside the undulator. After these modifications, we obtained an FEL power of 180° W in macro-pulse average at wavelength of 23 μn.
