Times Cited Count：0 Percentile：0.01(Nuclear Science & Technology)The Japan Atomic Energy Agency (JAEA) has designed a Transmutation Physics Experimental Facility (TEF-P) as an experimental facility in the Japan Proton Accelerator Research Complex (J-PARC). The TEF-P is a critical assembly driven by a low-power proton beam, a maximum of 10 W, which is extracted from a high-power beam source, such as 250 kW of 400 MeV proton beam of the J-PARC Linac. To extract such a low-power proton beam from the high-power proton beam, we developed a laser charge exchange (LCE) device and employed its technique, which is one of the non-contact beam extraction techniques. For the proof of performance of the LCE device to the TEF-P, a low-power proton beam was extracted using a negative-hydrogen (H
) Linac having an energy of 3 MeV, and a bright continuous laser. Proton beam with the power of 0.57 mW was successfully extracted with a laser stripping efficiency of 
. These experimental values are in good agreement with the estimated ones.

With the arrival of the latest generation of synchrotron sources and the introduction of advanced insertion devices, the high-energy (E 
30 keV) X-ray diffraction technique has become feasible, leading to new approaches in the quantitative study of the structure of disordered materials. Recently, the high-energy X-ray diffraction data have been combined with neutron diffraction data from a pulsed source to provide more detailed and reliable structural information than that hitherto available. We have developed a two-axis diffractometer for glass, liquid and amorphous materials at the SPring-8 high-energy X-ray diffraction beamline BL04B2. Furthermore, we have succeeded to analyze the intermediate-range order of network forming glasses, SiO
, BO
, and GeO by the reverse Monte Carlo (RMC) modelling technique with special focused on the ring structures using both high-energy X-ray and neutron diffraction data.

An introductory article of the published paper by G. Mourou and D. Umstadter "Extreme Light" in the Scientific American May 2002 issue is presented at the invitation of the Editor of Nikkei Science. One of the author Professor Mourou is the inventor of the main technology of the intense laser and is the leader of the research in High Field Science. Professor Umstadter, another author, is a laser acceleration experimentalist. In this article, an emphasis is put on the description of Japanese efforts in High Field Science of recent years and their ranking in the world is mentioned. The necessary attitude in advancing such frontier science is discussed.
