摘要:研究了在先进实验超导托卡马克(EAST)上,由低杂波(LHW)和离子循环射频(ICRF)加热实现高约束模式(H模)放电的等离子体中的电子热输运情况。通过计算得出,H模相比于L模(低约束模式)电子热输运系数显著下降,特别是在等离子体边缘地区。在典型炮号(33068#、38300#、40823#)中,归一化温度梯度特征长度(R/LTe)的阈值应该是3-11。这三炮的约束时间与电子热输运系数相关,当电子热输运系数越大时,约束时间越小。
Electron thermal transport in typical shots of high-confinement (H-mode) achieved with Lower Hybrid Wave (LHW) ,LHW and Ion Cycle Radio Frequency (ICRF) together is studied in EAST. The electron thermal conductivity during H-mode significantly decreases in comparison to L-mode, especially in the edge area. For these typical shots, the threshold value of R/LTe should be 3 to 11. The values of confinement time in three shots are related to the electron thermal conductivities. When the electron thermal conductivity is bigger, confinement time would be smaller.
