Hot ion mode was recently achieved at the Globus-M2 spherical tokamak when the toroidal magnetic field was as high as 0.9 T and plasma current 0.35 MA. The injection of two neutral beams with a total power of 0.7 MW and an energy of 30 keV into a plasma with major radius 0.36 m and minor radius 0.22 m (aspect ratio 1.6) made it possible to heat the plasma ions up to 4 keV, while electron density in the plasma center was as high as 8 × 1019 m−3. The achievement of high temperatures became possible due to the good thermal insulation of the plasma.

球形トカマクGlobus-M2において、トロイダル磁場が0.9 T、プラズマ電流が0.35 MAのときに、高温イオンモードが最近達成された。大半径0.36 m、小半径0.22 m(アスペクト比1.6)のプラズマへの、総パワー0.7 MW、エネルギー30 keVの2本の中性ビーム入射により、プラズマ中心部の電子密度が8 × 10¹⁹ m⁻³のとき、プラズマイオンを4 keVまで加熱することが可能となった。この高温達成は、プラズマの優れた熱遮蔽特性によるものである。
