摘要
HL-1装置上观测到大量放电破裂现象,其中一类出现在电流坪段的小破裂现象,在文献上讨论很少,其产生时的安全因子是2.5≤q_a≤4.5,密度为1×10^(13)cm^(-3)≤n<3×10^(13)cm^(-3)或n≥4×10^(13)cm^(-3), 在环压及软X射线上观测到几百毫秒的驰豫振荡。本文详细分析了这类现象的性质及特征,并讨论了其产生的原因。
The phenomena of minor disruptions during current flat phase have been observed in the HL-1 device for five years. When these phenomena appear the safety factors are 2.5≤qa≤4.5,and densities are 1 × 1013cm-3≤ n≤3×1013cm-3 or n≥4× 10I3cm-3. Periodic relaxation ocsillations of voltage and soft-X-rays are observed during minor disruptions. In the present paper, we carefully analyse their character and development conditions.
