A currentless plasma with a volume-averaged beta value of 2% has been produced with neutral beam heating. Target plasmas were created by second harmonic resonance heating with electron cyclotron waves (150–350 kW and 53.2 GHz) at a magnetic field strength of 0.94 T. Neutral beam injection (23–30 keV and 1.3−2.6 MW) was used to heat the plasma further. MHD stable and unstable high-beta plasmas were observed. The Q-mode plasmas were produced with the help of intense neutral gas puffing. Properties of the MHD activity and confinement of high-beta plasmas are discussed and compared with theoretical studies.

ベータ値が体積平均で2%の無電流プラズマが、中性粒子ビーム加熱によって生成された。ターゲットプラズマは、磁場強度0.94 Tにおいて電子サイクロトロン波(150〜350 kW、53.2 GHz)による第2高調波共鳴加熱によって生成された。中性粒子ビーム入射(23〜30 keV、1.3〜2.6 MW)は、プラズマをさらに加熱するために使用された。MHD的に安定な高ベータプラズマと不安定な高ベータプラズマの両方が観測された。Qモードプラズマは、強力な中性ガスパフの助けを借りて生成された。高ベータプラズマのMHD活動と閉じ込めの特性について議論し、理論的研究と比較する。
