Bagge, a student of Werner Heisenberg for his doctorate〔 1938 Doctorate: "Beiträge zur Theorie der schweren Atomkerne". See (Archive ) - Leipzig University.〕 and Habilitation,〔 1941 Habilitation: "Kernzertrümmerungen und schwere Teilchen in der kosmischen Strahlung". See (Archive ) - Leipzig University.〕 was engaged in German Atomic Energy research and the German nuclear energy project during the Second World War. He worked as an Assistant at the Kaiser-Wilhelm-Institut für Physik in Berlin. Bagge, who became associated professor at the University of Hamburg in 1948, was in particular involved in the usage of nuclear power for trading vessels, and he was one of the founders of the Society for the Usage of Nuclear Energy in Ship-Building and Seafare. The first German nuclear vessel, the "NS Otto Hahn", was launched in 1962. A research reactor was installed in Geesthacht near Hamburg at about the same time which has over the years formed into a center for materials research with neutrons. == Uranium enrichment == Dr. Bagge developed a gaseous uranium enrichment device (''Isotopenschleuse'' or ''isotope sluice'')〔'German National Socialism and the Quest for Nuclear Power, 1939-49', see (pp.133-135 ) by Mark Walker, published by Cambridge University Press, 1992.〕 for enriching the U-235 isotope content of uranium in 1944, using three methods; centrifugal force, electromagnetism and thermal diffusion. It was built by BAMAG-MEGUIN under the direction of Kurt Diebner. Yellow cake uranium oxide powder was reacted with hydrofluoric acid to form gaseous uranium hexafluoride. It was pumped into the sluice, which consisted of a centrifuge and spun at great speeds to fling heavier non-fissile 238U to the periphery. Electromagnets helped to keep 235U nearer the core of the centrifuge. Slight heating near the bottom of the "bowl" helped 238U to migrate to the bottom whilst 235U bubbled to the top of the chamber. Uranium hexafluoride gas with an enriched content of 235U was then sluiced off the top layers. Bagge got a patent in 1955 for the isotope sluice but it never achieved any economic importance. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Erich Bagge」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
