The Mega Amp Spherical Tokamak

M Cox, MAST Team1999年Fusion Engineering and DesignIF 1.7出版社

AbstractResults from START at Culham have been very impressive and have triggered the construction of several new Spherical Tokamaks (R/a≤1.5), including the Mega Amp Spherical Tokamak (MAST), which was given EURATOM approval in April 1996. MAST (R=0.7 m, a=0.5 m, k∼2, Ip≤2 MA) is twice the size of START and will allow plasmas with cross-section similar to medium-sized conventional tokamaks (e.g. ASDEX-U, D-IIID) to be studied. A summary is presented of the overall design of MAST, which as far as possible has been based on the successful approach used on START and has been arranged to maximise the use of existing COMPASS power supplies. Details of some of the challenging design issues associated with the components in the central regions of the machine, where space is restricted, are described.

カラムにおけるSTARTの成果は非常に印象的であり、R/a≤1.5の複数の新型球状トカマクの建設を促した。その中には、1996年4月にEURATOMの承認を得たメガアンペア球状トカマク(MAST)も含まれる。MAST(R=0.7 m、a=0.5 m、k∼2、Ip≤2 MA)はSTARTの2倍の規模であり、中規模の従来型トカマク(例:ASDEX-U、D-IIID)と同様の断面を持つプラズマの研究が可能となる。本稿では、可能な限りSTARTで採用された成功したアプローチに基づき、既存のCOMPASS電源の利用を最大化するように設計されたMASTの全体設計について概要を述べる。また、空間が制約される装置の中心領域における構成要素に関連するいくつかの困難な設計課題について詳述する。
