After the confirmation of the generation of the Compton backscattered X-rays with Nd:YAG laser and 150 MeV electron beam pulses at last fiscal year, we make some improvements for increase the generated X-ray flux. As one of them, we are developing the laser pulse compression with the stimulated Brillouin scattering (SBS) to obtain a high peak intensity of the Nd:YAG laser. As the SBS medium, we adopt a liquid fluorocarbon which has well achievements for the pulse compression at ILE at Osaka University. We aim the compressed pulse duration to be less than 1 ns. On this meeting we show the present status of the SBS pulse compression system for the Compton backscattering. In addition, we present the recent result of the Compton backscattering experiment without the laser compression technique.

Tungsten is one of the candidates for the divertor material of ITER because of its low retention and low hydrogen inventory. However, it is a problem that tungsten ions accumulated in a core plasma emit intense radiation and cool the plasma. For preparation of investigating the mechanism of the tungsten ion accumulation, Vaccum Ultra Violet (VUV) lines emitted from tungsten ions are identified. A VUV spectrum from a JT-60U plasma (
keV) is observed with a flat-field grazing-incidence spectrometer. The observed spectrum is compared with a theoretical spectrum calculated with Flexible Atomic Code. It is found that the observed peaks around 3 nm are due to transitions between 
levels of W
(
), and that those around 5, 6 and 13 nm are due to transitions between 
levels of W (
). It is believed that the former lines are useful to diagnose the tungsten ion accumulation in a high-temperature (
10 keV) plasma of ITER.

FeSrYCuO is known as the BaYCuO related super conducting compound with the substitution of the Fe for Cu, only when it is annealed in reduced atmosphere and subsequently in oxidized atmosphere. In this study, we have performed neutron powder diffraction of FeSrYCuO to investigate the magnetic disorder-ordering mechanism. No magnetic reflection was observed even below the magnetic transition temperature. This result indicated that the material has not long-range magnetic-ordering.

Local structure analysis of 0.75BiFeO-0.25BaTiO solid solution was carried out by a synchrotron radiation X-ray pair-distribution function (PDF) method with the temperature range from room temperature to 900
C. The 0.75BiFeO-0.25BaTiO occurred two phase transitions. The average structure of changed from low-temperature rhombohedral structure to pseudo-cubic structure at 500C, but the local structure unchanged. The local structure changed at second phase transition from pseudo cubic structure to cubic structure at 800
C. The local structure of the pseudo-cubic phase can be reproduced not by the average cubic structure but by the distorted rhombohedral structure.
