As cutting-edge technologies that support the science and technology of Japan, the X-ray Free Electron Laser （XFEL） and state-of-the-art high-performance general-purpose super computer are introduced here.

-X-ray Free Electron Laser （XFEL）

RIKEN Japan has already established the technology necessary to realize XFEL, and to develop the technology necessary to research its use, is building at present a prototype machine to oscillate vacuum ultraviolet laser of 60 nanometer （10-9） wavelength. This XFEL has the feature of a radiant light radiating strong X-ray, enabling the capture of short time phenomenon by using the characteristics of "laser," and is called "dream light." It is a technology to realize the structure analysis of atoms and molecules in a short period of time, the capture of faster movement and change, and higher preciseness of measurement, by enabling the free electron laser's high-energy and very short wave within the X-ray range.

By using such XFEL, structure analysis of one molecule in a giant protein or clarification of ultra high-speed phenomena of electron behavior in electronic parts will be possible. It will contribute to strengthening the international competitiveness of industries such as drug discovery and electronics and it is expected to improve conveniences and the health of people.

-State-of-the-art high-performance general-purpose super computer

Aiming at realizing the world's most efficient science, technology, and computer environment, the following developments are made：

（1）Development and dissemination of software to use its functions to the utmost extent
（2）Development and improvement of the world's most cutting-edge and most efficient general-purpose 10 petaflop computer system
（3）Formation of the world's top-level base for super computing research education with the above （2） as its core

Regarding a complicated and wide variety of phenomena in a wide range of areas, simulation of entire systems and sophisticated information processing and analysis become possible by using the super computer, and international leadership can be established in leading-edge super computing. It is also expected to contribute to the enforcement of competitiveness in science and technology and industry.

Furthermore, by the development and use of such state-of-the-art high-performance general-purpose super computer, the return of benefit to the society and economy, such as the building of a strong base for science and technology, new product development using nanotechnology and biotechnology, realization of new medical care by the fusion of multiple fields, and practical application of new disaster prevention or disaster decrease technologies is expected.
