Atitaniumhydride gun for plasma injection into the T2-reversed field pinchdevice

A V Voronin, K G Hellblom1999年Plasma Physics and Controlled FusionIF 2.2出版社

A study of a plasma gun (modified Bostic type) with titanium hydride electrodes has been carried out. The total number of released hydrogen atoms was in the range 1016-1018 and the maximum plasma flow velocity was 2.5×105 m s-1. The ion density near the gun edge reached 1.8×1020 m-3 and the electron temperature was around 40 eV as estimated from probe measurements. No species other than hydrogen or titanium were seen in the plasma line radiation. The plasma injector was successfully used for gas pre-ionization in the Extrap T2 reversed-field pinch device (ohmic heating toroidal experiment (OHTE)).

チタン水素化物電極を備えたプラズマガン(改良型ボスティック型)の研究が実施された。放出された水素原子の総数は10¹⁶〜10¹⁸の範囲であり、最大プラズマ流速は2.5×10⁵ m s⁻¹であった。ガン近傍のイオン密度は1.8×10²⁰ m⁻³に達し、電子温度はプローブ測定から推定して約40 eVであった。プラズマの線放射には水素またはチタン以外の種は観測されなかった。このプラズマインジェクターは、Extrap T2逆転磁場ピンチ装置(オーミック加熱トロイダル実験(OHTE))におけるガス予備電離に成功裏に使用された。
