The axially symmetric magnetic mirror device gas-dynamic trap (GDT, Budker Institute, Novosibirsk) has recently demonstrated a tangible increase in plasma electron temperature. According to laser scattering, a value of 0.4 keV has been achieved (a twofold increase). In addition to standard machine operation, utilizing a 5 MW neutral beam injection, a newly installed electron cyclotron resonance heating (ECRH) system was employed (54.5 GHz, 0.4 MW). The reported progress in electron temperature, along with previous experiments, which demonstrated plasma confinement at beta as high as 60%, is a significant advancement towards an energy efficient fusion neutron source based on GDT physics.

軸対称磁気ミラー装置であるガス動的トラップ(GDT、ブドカー研究所、ノボシビルスク)は、最近、プラズマ電子温度の顕著な上昇を実証した。レーザー散乱によると、0.4 keVの値が達成された(2倍の増加)。標準的な装置運転に加えて、5 MWの中性粒子ビーム入射を利用し、新たに設置された電子サイクロトロン共鳴加熱(ECRH)システム(54.5 GHz、0.4 MW)が使用された。報告された電子温度の進展は、ベータ値が60%もの高さでのプラズマ閉じ込めを実証した以前の実験とともに、GDT物理に基づくエネルギー効率の高い核融合中性子源に向けた重要な前進である。
