The structures of Eu complexes in the adsorbents prepared with various extractants were evaluated by ion beam induced luminescence analysis in an extraction chromatography for minor actinides recovery. The luminescence of Eu was measured with a proton beam obtained from the single-ended accelerator and an argon ion beam obtained from the azimuthally varying field cyclotron in Takasaki Ion Accelerators for Advanced Radiation Application in National Institutes for Quantum Science and Technology. In this study, it was confirmed that the spectral shape of Eu complexes in the adsorbents varied depending on the kinds of extractants, and the correlation between the change in the spectra and the structures of Eu complexes was investigated.

In an extraction chromatography method for minor actinides recovery, analysis for the structure of complex in a silica-based adsorbent has been studied to separate minor actinides efficiently. In this study, Eu was used as simulated material of minor actinides, and silica-based adsorbents containing Eu complex were prepared. The ion beam induced luminescence spectra of Eu complexes in silica-based adsorbents were measured, and the basic data for the structures of Eu complexes were obtained.

Kyoto University reports on the distance information display system developed in collaboration between "Fugen" and Kyoto University. In the distance information display system, the worker can easily measure the distance of the object. In this presentation, we report the test results carried out with "Fugen" and the questionnaire results of the subjects.

In this study, in order to make measuring lengths of the objects and the gaps at NPPs more efficient, the Distance Information Display System was developed, which make it easy for the dismantling workers to measure them. The results showed that the Distance Information Display System developed in this study can be used easily with extremely simple operation by the dismantling workers at NPPs, and the workers can also measure the lengths in a short time.

Magnetization distribution maps deduced from the measurement of polarization dependent cross-sections have provided unique information in understanding of the detailed electronic configurations in mixed valence materials and molecular magnets. Because of the limited neutron flux the method has been mostly applied to single crystal studies. In the advent of strong pulsed neutron source with intense high resolution powder diffractomer the magnetization distribution measurements by means of polarized neutron powder diffraction can become common place. The introduction of the high magnetic field may extend the applicability of the method to materials requiring high saturation field. In this lecture the polarized neutron powder diffraction experiment on FeN and -Fe fine particles performed in the frame work of "Ibaraki Prefecture Neutron Utilization Working Subgroup on nano-magnetic materials" will be presented and the possibility of the method will be discussed.
