Design of the Optical Components in the ITER Equatorial EC H CD Launcher

摘要

The optical components in the ITER Equatorial EC H&CD Launcher, i.e., the two mirrors including one steering mirror, are designed by considering the heat load on the mirrors, RF loss during the propagation from the Launcher inlet to outlet and the Electron Cyclotron Current Drive (ECCD) profile in the plasma. The allowable heat load on the steering mirror, which consists of stainless steel cooling pipe and CuCrZr body, is calculated for the optimization. The ECCD profile is also calculated. Both calculations are integrated into the launcher optimization program.
