[en] As a next generation experiment, we plan a neutrino oscillation experiment with baseline length of 295 km using 50 GeV proton synchrotron (PS) in Japan Hadron Facility, which has been approved and is being constructed, and Super-Kamiokande. Using the 0.75 MW PS, we expect about 2 orders of magnitude higher neutrino flux than K2K. This high intensity beam enables us to determine oscillation parameters in ν_μ disappearance and explore ν_e appearance with unprecedented precision and reach. Current design of the neutrino facility and its physics potential are introduced

[en] Experiments using secondary nuclear beams at the BEVALAC showed that light neutron-rich nuclei have interesting properties, such as the large nuclear matter radii (sometimes called a neutron halo) and soft E1 mode, which have not been seen for nuclei near the valley stability. In parallel with the theoretical works, experimentalists continued to study these in more detail by various methods. One direction is performing the experiments at intermediate-energy cyclotrons, such as MSU, GANIL, and RIKEN, where much higher beam intensity can be obtained. Second direction is the spectroscopic study of these nuclei using pions and Fermi-energy heavy ions. After the summary of the results from BEVALAC experiments, the author presents some new directions, such as the elastic scattering of ¹¹Li on hydrogen, exclusive measurement of ¹¹Li+Pb→⁹Li+n+n for the direct observation of the soft E1 mode, and the spectroscopy of ¹¹Li by pion double-charge-exchange reaction

[en] This article describes recent progress in high-temperature superconducting oxide electronics. Notable applications include (1) three-terminal superconducting transistors, (2) Josephson junctions, and (3) microwave and optical devices. Critical temperatures Tc higher than 77K are characteristic of oxide superconductors, and most applications are based on this feature. Another feature of this kind of material is the low carrier concentration, which is nearly the same order as that of degenerate semiconductors. A superconducting MIS electric field effect transistor has been obtained by using epitaxial oxide superconductor thin films. This article reviews high-Tc superconductor devices, particularly YBCO-MISFETs

[en] One of the PEC test was calculated by SALCON code to compare the calculation results with the experimental data as well as other analysis codes as a part of the IAEA/IWGFR/CRP on inter comparison of LMFBR seismic analysis codes. At first, features of SALCON code to minimize the computation time are described and then calculation model and condition are explained. As for the calculation result, the calculated displacements generally agreed well with the experimental data. The choice of 4% for the fraction of critical damping was found to be appropriate after evaluating the effect of damping. A reduction of dynamic freedom by Guyan reduction were found to be effective to minimize the computation time while maintaining reasonable accuracy. (author). 4 refs, 3 figs, 4 tabs

[en] Using the projectile fragmentation of exotic nuclear beams around 1 GeV/nucleon available at the LBL Bevalac, the nuclear structures of light nuclei near the neutron dripline have been studied. We report here on recent progresses concerning (1) the determination of the shape of the density distribution of neutron-rich nuclei with a neutron halo, (2) systematics of the momentum distribution of projectile fragments after a few neutron removal process, and (3) the extraction of electromagnetic dissociation cross sections which are related to the soft E1 mode in neutron-rich nuclei. We also report on (4) the direct observation of the soft giant dipole resonance in ¹¹Li via a pion double charge exchange reaction. (orig.)

[en] A mathematical model that simulates atmospheric freeze-drying for apple slices was developed based on the classical mass and heat balance equations. When operated above the glass transition temperature, product shrinkage and micro-collapse due to the glass-rubber transition occurred. So, instead of assuming formation of dried and frozen zones, a glassy matrix with particular vapor pressure was assumed. Apparent vapor pressure of apple slices in the glassy state was experimentally measured and summarized in a diagram, and the values in this diagram were employed for the simulation. This approach well predicted drying kinetics with reasonable accuracy with simplified equations. (Author)

[en] The intrinsic decay rate of orthopositronium formed in SiO₂ powder is measured using the direct 2γ correction method such that the time dependence of the pick-off annihilation rate is precisely determined using high energy-resolution germanium detectors. As a systematic test, two different types of SiO₂ powder are used with consistent findings. The intrinsic decay rate of orthopositronium is found to be 7.0396±0.0012(stat)±0.0011(sys) μs^-1, which is consistent with previous measurements using SiO₂ powder with about twice the accuracy. Results agree well with a recent O(α²) QED prediction, varying 3.8-5.6 experimental standard deviations from other measurements
