Fast electron dynamics in lower hybrid current drive experiment on HT-7 tokamak
HT-7托卡马克上低杂波电流驱动实验中的快电子动力学

Dynamic behaviour of fast electron in lower hybrid current drive (LHCD) experiment is a crucial issue in the sense of enhancing plasma performance. A new hard x-ray diagnostic system on HT-7 allows the investigation of the lower hybrid wave dynamics. The behaviour of fast electron is studied in several kinds of LHCD experiments, including long pulse discharges, high performance discharges and counter-LHCD experiments.
