Neutron guide tubes, which are installed near reactor cores, are damaged by neutrons and 
rays irradiation. Those glass substrates which contain boron material are affected by (n, 
) reaction, and ionization effect of rays on material strength decrease duration of use of neutron guide tubes. In order to increase resistance to radiation, we have fabricated a supermirror with Ni-P metallic substrate. The substrate roughness with 0.2 - 0.3 nm (rms) was produced by super- polishing. The neutron reflectivity reached 76 % for an m=3 supermirror.

Times Cited Count：8 Percentile：42.93(Chemistry, Physical)Ferroelectric BaTiO thin filmwith a thickness of 10ML were epitaxally grown on SrTiO (001) substrate by very slow deposition using MBE. The investigation were carried out by two growth methods: (i) codeposition and (ii) alternate deposition. In-situ observation of RHEED confirmed that an epitaxial cube-on-cube structure was prepared. After the deposition, X-ray diffraction measurements were carried out. The 10-ML-thick BaTiO films were highly 
-axis oriented single crystals with good film quality.
