当控制再分布尺度长度的参数变化时，磁约束等离子体的约束现象特征自然地从简单的沙堆算法中显现出来。密切的类似物被发现为增强的限制，边缘非线性，和边缘局域模式（ELMs），以及它们之间的定性相关性。这些结果表明，托卡马克观测雪崩运输有很深的联系存在增强约束和ELMs。
Confinement phenomenology characteristic of magnetically confined plasmas emerges naturally from a simple sandpile algorithm when the parameter controlling redistribution scalelength is varied. Close analogues are found for enhanced confinement, edge pedestals, and edge localised modes (ELMs), and for the qualitative correlations between them. These results suggest that tokamak observations of avalanching transport are deeply linked to the existence of enhanced confinement and ELMs.
