摘要:
RF power in the electron cyclotron (EC) frequency range is planned to be injected to the plasmas of China Fusion Engineering Test Reactor (CFETR). Numerical investigation for electron cyclotron current drive (ECCD) is performed under the parameters of the latest/final version of the CFETR concept design (R = 7.2 m, a = 2.2 m, BT = 6.5 T). The TORAY-GA ray-tracing code is used to optimize frequency and launcher ports of EC waves. It is found that both 240 GHz and 250 GHz EC waves can meet the desired current drive demand in the target radial reg...
