The GSI Helmholtz Centre for Heavy Ion Research ((ドイツ語:GSI Helmholtzzentrum für Schwerionenforschung)) is a federally and state co-funded heavy ion () research center in the Arheilgen suburb of Darmstadt, Germany. It was founded in 1969 as the Society for Heavy Ion Research ((ドイツ語:Gesellschaft für Schwerionenforschung)), abbreviated GSI, to conduct research on and with heavy-ion accelerators. It is the only major research center in the State of Hesse. The current director of GSI is Karlheinz Langanke who succeeded Horst Stöcker in 2015. The laboratory performs basic and applied research in physics and related natural science disciplines. Main fields of study include plasma physics, atomic physics, nuclear structure and reactions research, biophysics and medical research. The lab is a member of the Helmholtz Association of German Research Centres. Shareholders are the German Federal Government (90%) and the State of Hesse (10%). As a member of the Helmholtz Association, the current name was given to the facility on 7 October 2008 in order to bring it sharper national and international awareness.〔(Pressemitteilung des GSI Helmholtzzentrums für Schwerionenforschung vom 20. Oktober 2008 ) 〕 ==Primary research== The chief tool is the heavy ion accelerator facility consisting of UNILAC, the Universal Linear Accelerator (energy of 2 - 11.4 MeV per nucleon), SIS 18, the heavy-ion synchrotron (0.010 - 2 GeV/u) and ESR, the experimental storage ring (0.005 - 0.5 GeV/u) and FRS. The UNILAC was commissioned in 1975, the SIS 18 and the ESR were added in 1990 boosting the ion acceleration from 10% of light speed to 90%. Elements discovered at GSI: bohrium (1981), meitnerium (1982), hassium (1984), darmstadtium (1994), roentgenium (1994), and copernicium (1996). 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「GSI Helmholtz Centre for Heavy Ion Research」の詳細全文を読む スポンサード リンク
