摘要
用简化的再循环模型和破裂模型,研究了边缘发生的电离与电荷交换的能量损失与密度极限破裂的关系,得到HL 1M装置的临界破裂密度nc≤1.6×1020m-3。
Tokamak plasma discharge disruption at high density is investigated.The instability analysis indicates that the disruption result from the energy loss arising from hydrogen recycling at the edge of the plasma.This energy loss can cause contraction of the current channel and the production of a disruptively unstable configuration.Using a simple model,implications of recycling are investigated for disruptions in the HL-1M tokamak.The critical high-density n_c≤1.6×10~20m^-3 is reached.
