The Ernst Ruska-Centre (ER-C) for Microscopy and Spectroscopy with Electrons is a German research establishment conjointly operated by the Jülich Research Centre and RWTH Aachen University on a pari passu basis. The facility, which also offers user services to external research groups, is located on the campus of Research Centre Jülich belonging to the Helmholtz Association of German Research Centres. The ER-C's main purposes are fundamental research in high-resolution transmission electron microscopy method development as well as respective applications coming along with topical problems in solid state research and energy research. For theses purposes the ER-C runs several state-of-the-art transmission electron microscopes and develops customed software solutions to be used for e.g. for the exit wave retrieval purposes or the measurement of higher-order lens aberrations. The ER-C was founded in Aachen on 27 January 2004〔(Press Release: Foundation of the Ernst Ruska-Centre )〕 by means of a contract signed by the chairman of Forschungszentrum Jülich Joachim Treusch and RWTH Aachen University's rector Burkhard Rauhut. The centre was inaugurated on 18 May 2006 in presence of members of the Ernst Ruska family as well as representatives of the international electron microscopy community.〔(Press Release: Inauguration of the Ernst Ruska-Centre )〕 ==Instrumental Resources== The ER-C presently houses 13 electron microscopes manufactured by FEI Company and JEOL Ltd. ranging from standard scanning electron microscopes to highly specialised Titan series transmission electron microscopes equipped with aberration correction units and offering an information limit well below 100 picometres. The majority of ER-C instrumental resources is available for use by both in-house and external users. On 12 December 2008 the ER-C and FEI Company announced that a next generation electron microscope with a record resolution of 50 picometres will be made available to a broad user community from 2010.〔(Press Release: Globally most Powerful Microscope to be Installed in Jülich )〕 The instrument known as PICO, which is equipped with a special unit allowing for the correction of the chromatical aberration for the first time in electron microcopy,〔(Animation: PICO - How it works )〕 allows to see details measuring only a fraction of an atomic diameter and thus at the absolute limits of optical systems. This enables atomic structures for materials in energy research and microelectronics to be investigated more precisely than has ever been possible before. On 4 November 2009 work began on an extension to the ER-C to house the PICO microscope with a groundbreaking ceremony〔(Press Release: Work Begins on Laboratory for World's Most Powerful Electron Microscope )〕 and the building was formally inaugurated on 29 September 2011. The PICO microscope was inaugurated on 29 February 2012.〔(Press Release: PICO - Unique electron microscope inaugurated )〕 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「Ernst Ruska-Centre」の詳細全文を読む スポンサード リンク
