Benchmarking ICRF full-wave solvers for ITER

Benchmarking full-wave solvers for ion-cyclotron range of frequency (ICRF) simulations is performed using plasma profiles and equilibria obtained from integrated self-consistent modelling predictions of four ITER plasmas. One is for a high-performance baseline (5.3 T, 15 MA) DT H-mode. The others are for half-field, half-current plasmas of interest for the pre-activation phase with bulk plasma ion species being either hydrogen or He ⁴. The predicted profiles are used by six full-wave solver groups to simulate the ICRF electromagnetic fields and heating, and by three of these groups to simulate the current drive. Approximate agreement is achieved by four of the solvers for the heating power partitions for the DT and He ⁴ cases. Factor of two or more disagreements are found for the heating power partitions for the cases with second harmonic He ³ heating in bulk H cases. Approximate agreement is achieved simulating the ICRF current-drive 1D profiles.
