Experimental study of large power lower hybrid current drive on HT-7 tokamak

  • 摘要: 在HT-7超导托卡马克成功进行了大功率(P_(LHW)=100-800 kW,f=2.45 GHz)低混杂波电流驱动实验.研究了不同入射功率和等离子体密度下的低混杂波电流驱动效率.获得了以平均电子密度增加、氘阿尔法(D_α)线辐射减少为特征的粒子约束改善;粒子约束时间τ_p增加了约1.5倍.仔细研究了能量约束时间与等离子体密度和低混杂波功率的关系.
    Abstract: Large power current drive of lower hybrid wave (LHW) was performed (P_(LHW) 100-800 kW at 2.45 GHz) recently in the HT-7 tokamak. The lower hybrid current drive ( LHCD) efficiency is studied for different injected powers and for different densities. Improved particle confinement is observed by application of LHCD as characterized by an increase of central line average electron density and decrease of D_α emission. The particle confinement time τ_P increased about 1.5 times compared with ohm discharge. The dependence of energy confinement time τ_E on plasma density and LHW power is experimentally studied in detail.
