论文摘要
Jorek 3D非线性磁流失动力学(MHD)在ITER中进行了纯氘碎片注射的模拟。结果表明,这样的方案可以允许血浆稀释超过因子10,而不会立即触发大型MHD活性,前提是背景杂质密度足够低。这似乎是一种有希望的策略,是降低热尾巴流电子(RE)生成的风险,并避免在ITER中完全束缚,从而激发了这一方向的进一步研究。
JOREK 3D non-linear MagnetoHydroDynamic (MHD) simulations of pure Deuterium Shattered Pellet Injection in ITER are presented. It is shown that such a scheme could allow diluting the plasma by more than a factor 10 without immediately triggering large MHD activity, provided the background impurity density is low enough. This appears as a promising strategy to reduce the risk of hot tail Runaway Electron (RE) generation and to avoid RE beams altogether in ITER, motivating further studies in this direction.
