Effect of gas recycling and secondary electron emission on the axial power flow in an open-ended device

G.D. Porter1982年被引用 24Nuclear FusionIF 3出版社

A model analyses the effect of secondary electron emission and gas recycling on open-ended fusion devices. Secondary emission is assumed to be limited by space-charge effects. It is also assumed that cold plasma is created by the ionization of gas recycled from the end wall. The axial power flow in the device was increased by these phenomena. This article shows that fairly simple techniques can control the enhancement of the power losses. The results of this model are in agreement with measurements made on the TMX experiment. Estimates made for the TMX Upgrade and MFTF-B indicate that these effects will not significantly enhance the axial power losses.

モデルは、開放端型核融合装置における二次電子放出とガスリサイクリングの影響を解析する。二次電子放出は、空間電荷効果によって制限されると仮定される。また、端壁からリサイクリングされたガスによって冷たいプラズマが生成されると仮定される。これらの現象により、装置内の軸方向パワーフローが増加した。本論文は、比較的単純な手法でパワー損失の増大を制御できることを示す。このモデルの結果は、TMX実験での測定結果と一致する。TMXアップグレードおよびMFTF-Bに対する推定では、これらの効果が軸方向パワー損失を有意に増加させないことが示される。
