托卡马克装置上电磁负载大小值与破裂期间电流猝灭特征有密切的关系。电流猝灭特征包括电流猝灭波形以及电流猝灭率等,它将在一定程度上决定装置的寿命。本文选取100%-40%,90%-10%,80%-20%三个区间分析了HL-2A装置上等离子体破裂现象,得到三个不同区间下电流猝灭参数范围。对比分析结果表明:在相同定义下,利用100%-40%和80%-20%区间得到的平均电流猝灭时间以及电流猝灭率分布差异最小。除了80%-20%区间外,100%-40%区间也可作为提供最大线性平均等离子体电流猝灭速率近似的适合区间。 |

The value of electromagnetic load is closely related to the current quench characteristics in the tokamak during plasma disruption. The characteristics includes the current quench waveform and current quench rate, it determines the life of the Tokamak device to a certain extent. The spontaneous disruption data of the HL-2A are statistically analyzed by using three different intervals of 100%-40%, 90%-10% and 80%-20%, and the statistical results are compared and analyzed. The statistical results show that: Under the same definition, not only the average current quenching time and current quenching rate distribution have the least difference between 100%-40% and 80%-20%, but also the average current quenching time and current quenching rate statistical distribution almost are the same. In addition to the 80%-20% range, the 100%-40% range can also be used as a suitable range to provide an approximation of the maximum linear average plasma current quenching rate. |
