LEIR was first proposed in 1993〔http://cdsweb.cern.ch/record/279362/files/〕 but it wasn't until 2003 that work to transform the old experiment in to the new accelerator was started. The upgrade took just over two years being commissioned in October 2005〔http://cerncourier.com/cws/article/cern/29480〕〔http://accelconf.web.cern.ch/AccelConf/e06/PAPERS/WEOBPA02.PDF〕 and tested for 4 months. In Autumn 2006 it was used to re-commission the PS to handle ions and then again a year later it was used to re-commission the SPS. However it wasn't until November 2010, five years later, that it successfully carried out its primary role to provide the lead ions to the LHC for its first ion collisions.〔http://www.telegraph.co.uk/science/large-hadron-collider/8116226/Large-Hadron-Collider-creates-mini-Big-Bang-with-lead-ions.html〕 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「Low Energy Ion Ring」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.
