Status of the Russian pellet injector R&D program for plasma fuelling

I Viniar2000年Fusion Engineering and DesignIF 1.7出版社

AbstractBasic trends of research within the Russian pellet injector R&D program for 1999–2001 are discussed. The attention is focused on injectors with a screw extruder and those with a porous generator capable of injecting pellets in a repetitive continuous steady state mode. Over 12 000 deuterium pellets of 2 mm diameter were produced and accelerated to 200 m/s at a rate of 10 Hz with a reliability over 99% by a pneumatic injector equipped with a screw extruder. Over 2000 hydrogen pellets of 2.4 mm diameter and 4 mm length were accelerated to 1 km/s at a rate of 0.3–0.8 Hz by a pneumatic injector equipped with a porous generator with no moving parts. The injector designs and experimental results are presented and a concept of a new centrifuge pellet injector is discussed.

ロシアのペレット入射器研究開発プログラムにおける1999年から2001年までの研究動向について考察する。スクリュー押出機を備えた入射器と、多孔質生成器を備え、繰り返し連続定常状態でペレットを入射できる入射器に焦点を当てる。スクリュー押出機を備えた空気圧式入射器により、直径2 mmの重水素ペレットを12,000個以上生成し、毎秒10回の速度で200 m/sまで加速し、信頼性は99%以上であった。可動部品のない多孔質生成器を備えた空気圧式入射器により、直径2.4 mm、長さ4 mmの水素ペレットを2,000個以上、毎秒0.3~0.8回の速度で1 km/sまで加速した。入射器の設計と実験結果を示し、新しい遠心式ペレット入射器の概念について議論する。
