A vented pump limiter for the reversed field pinch RFX

P. Sonato1998年Fusion Engineering and DesignIF 1.7出版社

AbstractThe reversed field pinch (RFP) plasma performance, as in the Tokamak, is strongly correlated with the edge neutral particle control. The drawbacks of the conventional magnetic divertors and throat limiters on the RFP plasma have slackened the application of an active particle control system in existing devices. An advanced solution, based on the idea of the `vented pump limiter' experimented on Tore Supra, has been conceived for RFX. This type of pump limiter is very attractive for a RFP. In this paper, the design of a `vented limiter' prototype for RFX is presented. Up to six modules of this limiter can be installed at the equatorial plane of RFX, allowing a particle exhaust efficiency comparable with a divertor or a throat limiter working in a Tokamak. Finally, the optimization of this concept for the next step RFP device is presented.

反転磁場ピンチ(RFP)プラズマの性能は、トカマクと同様に、周辺部における中性粒子制御と強く相関している。従来の磁気ダイバータやスロートリミッタは、RFPプラズマにおける能動的な粒子制御システムの適用を制限してきた。Tore Supraで実験された「ベンテッド・ポンプリミッタ」の概念に基づく先進的な解決策が、RFXのために考案された。このタイプのポンプリミッタはRFPにとって非常に魅力的である。本論文では、RFX用の「ベンテッド・リミッタ」プロトタイプの設計について述べる。このリミッタは最大6モジュールまで赤道面に設置可能であり、トカマクにおけるダイバータやスロートリミッタと同等の粒子排気効率を達成できる。最後に、次世代RFP装置に向けたこの概念の最適化について述べる。
