Times Cited Count：8 Percentile：42.19(Engineering, Electrical & Electronic)To investigate whether one dimensional pinning centers (1D PCs) can attain the isotropic critical current density (
) properties, columnar defects (CDs) crossing at widespread angles were installed by heavy-ion irradiations into YBCO thin films. For the sample containing the CDs crossing relative to the 
-axis, the plateau-like behavior of 
is realized over a wide range of magnetic field orientations, except for around B 
-plane where a dip structure is accompanied by a rapid decline of the . For the bimodal splay configuration consisting of CDs crossing relative to the -axis, a single peak around the -axis is observed in the angular dependence of , suggesting the splay effect at B -axis by the crossed CDs. Two parallel families of CDs crossing relative to the -plane, on the other hand, bring about not a peak but a dip around B -plane on the angular dependence of .

Times Cited Count：1 Percentile：10.22(Nuclear Science & Technology)Previously DT neutronics experiments were performed by using partial blanket mockups for Japanese ITER test blanket module at JAEA FNS, and tritium production rates (TPR) inside blanket mockups were measured in details. The calculation with the nuclear data library FENDL-2.1 and Monte Carlo code MCNP4C agreed well with most of the measured TPRs within uncertainty of 10%. On the other hand, overestimations were found for the TPR in the experiment with a reflector and the TPR around the boundary between the rear part of the breeder layer and the beryllium layer by more than 10%. In order to confirm this concern, we measured reaction rate distribution in the partial blanket mockups with DT neutrons with two solid breeder blanket partial mockups, (Be/Li
TiO
/Be, SS316/LiTiO/SS316). Experiments were performed with and without a neutron source reflector. In order to measure reaction rate distributions, the activation foil method was applied using Nb and Au foils in this study. Experimental analyses were performed by MCNP4C with FENDL-2.1. Calculation results to experimental ones (C/Es) on the Au reaction rate with a reflector were larger than those without one. Detailed results are presented in this conference.
