Potential-dependent surface structures of Au(111) and Au(100) single-crystal electrodes in a 50 mM H$$_{2}$$SO$$_{4}$$ solution were investigated at an atomic level using in situ surface X-ray scattering (SXS) techniques. It was confirmed that both the Au(111) and Au(100) surfaces were reconstructed with an attached submonolayer of an oxygen species, most probably water, at 0 V (vs Ag/AgCl). Results at +0.95 V supported a previously suggested model for both the Au(111) and the Au(100) electrodes that, based on infrared and scanning tunneling microscopy measurements, the surfaces were a (1$$times$$1) structure with the coadsorbed sulfate anion and hydronium cation (H$$_{3}$$O$$^{+}$$). At +1.05 V, where a small amount of an anodic current flowed, adsorption of a monolayer of oxygen species was observed on both surfaces.

This report describes the studies done through spectroscopic method of high-energy $$gamma$$ ray to determine neutron capture cross sections of radioactive nuclides, in FY2004 at the Research Reactor Institute, Kyoto University. The following three items are described. (1) Development of a method to determine thermal neutron capture cross sections by prompt $$gamma$$-ray measurements, (2) Evaluation of a large BGO detector system as a total-energy detector, and (3) neutron capture cross-section measurements by TOF method.

The Engineering Design Activities (EDA) for the International Thermonuclear Experimental Reactor (ITER) was performed under the collaboration of Japan, EU, Russia and the US. The EDA was successfully completed in July 2001, in which the development of fabrication technology for advanced components, such as superconducting coils, was conducted. The ITER magnet system consists of Toroidal Field coils, a Central Solenoid (CS), Poloidal Field coils and Correction coils. The construction of these coils requires advanced technologies that fairly exceeded those available at the start of the EDA. Therefore, CS Model Coil and TF Model Coil projects were implemented. To fabricate the CS Model Coil, the fabrication technologies for high performance strand, large cable, winding, heat treatment, joint and insulation are indispensable. This report describes the above detailed fabrication technologies successfully developed in the CS Model Coil Project.
