Times Cited Count：6 Percentile：44.02(Materials Science, Multidisciplinary)Fuel retention rates and carbon re-deposition rates in the plasma shadowed areas in JT-60U were measured. Distributions of the fuel retention as well as the carbon re-deposition in the whole in-vessel of a large tokamak were clarified for the first time in the world. The fuel retention in the plasma shadowed areas was about two times larger than that in the carbon re-deposited layers on the plasma facing surface, although the amount of the carbon re-deposited on the plasma shadowed areas were about a half of that on the plasma facing surface, because of relatively lower temperature in the shadow areas causing higher hydrogen saturation concentration in the carbon re-deposited layers. The total fuel retention rate in JT-60U, including previously measured for all plasma facing areas, was evaluated to be 1.3

, which was lower than that in other devices, due to probably to higher temperature operation in JT-60U.

The resonant and non-resonant two-photon single ionization processes of He were investigated using intense free electron laser light in the extreme ultraviolet (XUV) region (53.4-61.4 nm) covering the 1s-2p and 1s-3p resonant transitions of He. On the basis of the dependences of the yield of He
on the XUV light-field intensity at 53.4, 58.4, 56.0 and 61.4 nm, the absolute values of the two-photon ionization cross sections of He at the four different wavelengths and their dependence on the light-field intensity were determined for the first time.

We performed resonant inelastic X-ray scattering at Cu-K absorption edge to study charge excitations in hole-doped high-Tc cuprate La(Sr,Ba)CuO. By subtracting elastic and molecular orbital excitation components from RIXS spectra, we have found dispersing charge excitation below 4 eV. This is the first success of observation of intra-band excitation which reflects dynamical charge-charge correlation function in the hole-doped system.

-hexaoctylnitrilotriacetamide (HONTA) is one of the extractants that form complexation with minor actinides (Am
, for example). The initial reaction of radiolysis, whether it is direct or indirect, is ionization of HONTA after interaction with electrons. In this study, VUV and soft X-ray were irradiated to HONTA on the gold plate, and the released electrons were energy analyzed and detected by SCIENTA to acquire the photoelectron spectra. The quantum chemical calculations were performed to evaluate the electronic structure and ionization energy of HONTA. For future works, these results will be applied to the molecular dynamics simulation in order to elucidate radiolysis.
