| 内容記述 | In fusion reactor, large transient heat load attributed to the edge localized mode (ELM) could damage the diverter plate. Therefore, it is needed to mitigate or supress the ELM amplitude and an application of the resonant magnetic perturbation (RMP) field is thought to be one of effective solutions. Because the RMP field has three-dimensional (3D) geometry, 3D plasma fluid transport and kinetic neutral transport code, ''EMC3-EIRENE'' is suitable to model the RMP effect on steady-state parameters. In previous researches, EMC3-EIRENE simulations of RMP effects are conducted in several devices such as NSTX, AUG, and ITER. The construction of JT-60SA was completed in 2020, and various experiments will be conducted with RMP. Recently, although an EMC3-EIRENE modeling was firstly performed in JT-60SA, the applied RMP condition was only one case. Therefore, this study perform numerical simulations with several RMP strengthes in JT-60SA. The divertor heat flux profiles with RMP coil currents of Ic = 0 (without RMP), 10, 20, and 30 kA are simulated. Here, plasma responce is not considered. Except for Ic = 0 case, the strike-point splitting patterns are found with the toroidal mode number of n = 3, which is the same of that of the RMP. Furthermore, by increasing the RMP coil current, enhancement of the splitting is found. We will present detailed relationships between the RMP strength and edge and divertor plasma parameters. |
