Studies have been carried out of an MHD stable rotating plasma with the following parameters: mean ion energy up to 40 keV in the laboratory frame of reference or up to 20 keV in the rotating frame of reference, plasma density 3 × 1011 cm−3 (and up to 1012 cm−3 in special regimes), mean energy of electrons 0.1−1.0 keV (non-Maxwellian spectrum), lifetime of ions 10−4 s (determined by charge exchange), and plasma volume 0.1 m3, in experiments on the PSP-2 device. The field strength in the plasma was about 20 kV/cm, and the total voltage achieved 0.5 MV. The MHD stabilization conditions are in agreement with the theoretical estimates. A hot plasma was created in a high voltage × discharge, the cold hydrogen gas having been puffed without any heating or plasma injection systems.

PSP-2装置での実験において、以下のパラメータを持つMHD安定回転プラズマの研究が行われた:実験室座標系での平均イオンエネルギーは最大40 keV、回転座標系では最大20 keV、プラズマ密度は3×10^11 cm^-3(特別な条件下では10^12 cm^-3まで)、平均電子エネルギーは0.1〜1.0 keV(非マクスウェルスペクトル)、イオン寿命は10^-4秒(電荷交換による)、プラズマ体積は0.1 m^3。プラズマ中の電界強度は約20 kV/cm、全電圧は0.5 MVに達した。MHD安定化条件は理論的見積もりと一致している。高温プラズマは、高電圧 × 放電によって生成され、冷たい水素ガスは加熱やプラズマ入射システムなしでパフされた。
