    EAST装置H模时的电子热输运系数

    Electron Thermal Conductivity in H-mode in EAST

    • 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。

       

      Abstract: 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.
