摘要

Lower hybrid current drive (LHCD) experiments have been carried out to achieve high performance for long pulse operation in the HT-7 superconducting tokamak. Multifaceted asymmetric radiation from the edge (MARFE) phenomena is summarized and studied in the HT-7 tokamak. MARFE during LHCD discharge often occurs at the value of Z_eff^{1 / 2} f_GW in range of 0.6-0.9. These MARFEs generally appear to have the same characteristics as high f_GW density MARFEs and are locally stable throughout the LHCD pulse. The MARFE instability typically occurs at a fraction 33% of the n_GW density during LHCD discharge, and it can often terminate the long pulse discharges in the HT-7 tokamak.
