AbstractTPE-RX is a large-sized reversed-field pinch machine newly constructed at the Electrotechnical Laboratory. In this paper the design concepts, procedures to determine the machine size and the flux swing to drive the plasma current, and the prediction of the global confinement properties of the TPE-RX are reported. From these considerations, major and minor radii (R, a) are decided to be R/a=1.7175/0.45 m, respectively. It is estimated that the flux swing of the iron core of more than 3.9 Wb is necessary to drive 1 MA of plasma current, Ip, which is the given constraint of the machine. Energy confinement time in the range of 3–18 ms is predicted to be attained at Ip=1 MA depending on the models and assumptions.

AbstractTPE-RXは、電子技術総合研究所で新たに建設された大型の逆転磁場ピンチ装置である。本論文では、設計概念、装置規模の決定方法、プラズマ電流を駆動するための磁束掃引、およびTPE-RXの全体閉じ込め特性の予測について報告する。これらの検討から、主半径および副半径はR/a=1.7175/0.45 mと決定された。1 MAのプラズマ電流(Ip)を駆動するためには、鉄芯の磁束掃引として3.9 Wb以上が必要であると見積もられた。閉じ込め時間は、モデルおよび仮定に依存して、Ip=1 MAにおいて3〜18 msの範囲で達成されると予測された。
