翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク China spallation neutron source ： ウィキペディア英語版 China spallation neutron source The China Spallation Neutron Source is a proposed accelerator-based neutron source, operated by the Institute of High Energy Physics, to be built at Dongguan in Guangdong province - the first major scientific facility in south China. The project was approved by Chinese central government in 2005; it is intended to start construction in 2010, commissioning in 2016, and operation in 2018. The source contains a proton synchrotron fed by a linear accelerator; short (<500ns) pulses of 1.63e13 1.6GeV protons are extracted from the synchrotron 25 times a second;〔http://csns.ihep.ac.cn/english/Introduction/Introduction.htm〕 these pulses strike a tungsten-metal target (cooled with heavy water) to produce energetic neutrons, which are reduced to scientifically-interesting energies by a variety of moderators. The intended budget for the project is 1.5 billion CNY;〔http://accelconf.web.cern.ch/AccelConf/a07/PAPERS/WEZMA02.PDF〕 this limits the initial power of the machine to about 120 kW, but it has been designed so that its power can readily be quadrupled if more funding becomes available, by upgrading the linear accelerator and the RF components of the synchrotron. ==References== 〔 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「China spallation neutron source」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.
