JAEA has had many kinds of meetings for technology exchange willingly as an activity to widely make use of the accumulation of the results of research and development on the way to develop FBR "Monju" in general industry. In this report, one of the local traditional industries of Fukui Prefecture, "Echizen pottery" is featured to show an activity of technological exchange. JAEA established a "technological exchange group on Echizen pottery" to scientifically find out the process until firing ends by analyzing behaviors including temperature distribution and flow condition of the inside of anagama with an analyzing technology (thermal Hydraulics), one of our representative research results. This is a report to show the content which has been discussed and evaluated based on the results of firing experiments and their analysis in this group.

Times Cited Count:3 Percentile:17.92(Physics, Applied)In the high- research, relationship between the pseudogap and the superconducting gap has been an important issue. We have performed a detailed temperature-dependent angle-integrated photoemission study of lightly-doped to heavily-overdoped LaSrCuO and oxygen-doped LaCuO. We found that, while the magnitude of the pseudogap increased with decreasing doping, that of the superconducting gap did not increase. This behavior can be explained if the superconducting gap opens only on the Fermi arc around the node (0,0)-(,) whereas the pseudogap opens primarily around (,0).

Times Cited Count:66 Percentile:88.66(Materials Science, Multidisciplinary)We have performed a temperature-dependent angle-integrated photoemission study of LaSrCuO covering from lightly doped to heavily overdoped regions and oxygen -doped LaCuO. The superconducting gap energy was found to remain small for decreasing hole concentration while the pseudogap energy and temperature increase. The different behaviors of the superconducting gap and the pseudogap can be explained if the superconducting gap opens only on the Fermi arc around the nodal (0,0)- direction while the pseudogap opens around . The results suggest that the pseudogap and the superconducting gap have different microscopic origins.
