在大螺旋装置的局部岛（m/n = 1/1）偏滤器放电中，当注入一系列弹丸时，产生稳定的超致密芯等离子体。密度高达4.6 × 1020 m-3且温度为0.85 keV的核心区域由具有非常高密度梯度的内部扩散势垒维持。在岛动力学的研究中，我们发现，一个外部强加的大岛（m/n = 1/1），大到15%的小半径愈合时，β在岛上超过一个临界值。
In local island (m/n = 1/1) divertor discharges in the large helical device a stable super dense core plasma develops when a series of pellets are injected. A core region with a density as high as 4.6 × 1020 m−3 and a temperature of 0.85 keV is maintained by an internal diffusion barrier with a very high density gradient. In a study of island dynamics, we find that an externally imposed large island (m/n = 1/1) as large as 15% of the minor radius is healed when beta at the island exceeds a critical value.
