在Wendelstein 7-AS(W7-AS)上,以超过3 × 1020 m−3的极高密度成功地进行了二次、三次和四次谐波140 GHz电子伯恩斯坦波(EBW)的加热实验。EBW是通过OXB模式转换产生的。在1 × 1020 m−3的中等密度下,第一次可以在过密度等离子体中证明一次谐波70 GHz EBW的有效电流驱动。
Successful heating experiments with second, third and fourth harmonic 140 GHz electron Bernstein waves (EBWs) were performed at an extremely high density of above 3 × 1020 m−3 at Wendelstein7-AS (W7-AS). The EBWs were generated by OXB-mode conversion. At medium densities of 1 × 1020 m−3, efficient current drive with first harmonic 70 GHz EBWs could be demonstrated in an overdense plasma for the first time.
