The most promising concept for deep fuelling a reactor is by the injection of compact toroid (CT) plasmoids. The first results showing CT fuelling of a tokamak plasma, without any adverse perturbation to the tokamak discharge, are reported. The Compact Toroid Fueller (CTF) device was used to inject a CT-spheromak plasmoid into the TdeV tokamak. Following the CT penetration, the tokamak particle inventory increased by 16%, the loop voltage and the plasma current did not change, and there was no increase in magnetohydrodynamic (MHD) activity. The number of injected impurities was low and dominated by non-metallic elements. The plasma diamagnetic energy and the energy confinement time increased by more than 35%

深部燃料供給のための最も有望な概念は、コンパクトトロイド(CT)プラズモイドの注入である。トカマク放電に対する悪影響を伴わない、トカマクプラズマへのCT燃料供給の最初の結果を報告する。コンパクトトロイド燃料供給装置(CTF)を用いて、CTスフェロマックプラズモイドをTdeVトカマクへ注入した。CTの貫入後、トカマクの粒子インベントリは16%増加し、ループ電圧とプラズマ電流は変化せず、磁気流体力学(MHD)活動の増加も見られなかった。注入された不純物の数は少なく、非金属元素が支配的であった。プラズマの反磁性エネルギーとエネルギー閉じ込め時間は35%以上増加した。
