Benchmarking ICRF Full-wave Solvers for ITER

Abstract

Benchmarking of full-wave solvers for ICRF simulations is performed using plasma profiles and equilibria obtained from integrated self-consistent modeling 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 for the predicted heating power for the DT and He 4 cases. Factor of two disagreements are found for the cases with second harmonic He 3 heating in bulk H cases. Approximate agreement is achieved simulating the ICRF current drive.
