本文介绍了从高磁场侧注入固体氘丸对ELMy H模式托卡马克放电进行高效率换料的方法。与标准低场侧喷相比，燃料效率提高了4倍，弹丸侵彻量提高了2倍以上。这一实验结果可以定性地解释为：磁场力将反磁性等离子体云推向低磁场，导致浅低场侧注入的粒子快速损失，但提高燃料效率和高场侧注入的弹丸穿透。
High-efficiency refuelling of ELMy H-mode tokamak discharges with solid deuterium pellets injected from the magnetic high-field side is demonstrated. Compared to standard low-field side injection, the fuelling efficiency was enhanced by a factor of 4, the pellet penetration more than 2 times. This experimental result can be qualitatively explained by the magnetic force pushing a diamagnetic plasma cloud towards lower magnetic field, causing rapid particle loss for shallow low-field side injection, but enhancing fuelling efficiency and pellet penetration for high-field side injection.
