Plasmas have widely been utilized for scientific and engineering applications, such as nuclear fusion, nanofabrication, material processes, medical therapy, environmental treatment and electric thruster. In order to realize innovative plasma technology, we have been  developing novel plasma sources (arcjet plasmas, plasma windows) and investigating their characteristics by plasma spectroscopy based on the quantum mechanics.
   In addition, for applications to X-ray microscopy and X-ray lithography, bright laser driven plasma X-ray sources have been developed and suceeded in significant enhancement of water wavelength X-ray radiation. Coherent plasma X-ray laser and high-order hamonics based plasma X-ray lasers has also been carried out as an international collaboration research with Japan and EU.
