Finite element simulation of ICRF wave heating of core and edge plasmas in EAST

Year: 2026

Type: conference-paper

Abstract: In recent years, simulations using the finite element method (FEM) have been conducted to study ion cyclotron resonance heating (ICRH) in the EAST tokamak (including SOL plasma). This paper improves the previous FEM for solving the perpendicular wavenumber [ Nucl. Fusion. 62. 7 076032 (2022)], aiming to correct the local deviation in solving the perpendicular wavenumber of cold plasma fast waves. Results show that ion cyclotron resonance heating of the minority ion H dominates energy absorption in the plasma core. The power absorption characteristics of ICRF waves are consistent with previous findings, with potential errors possibly caused by fast wave reflection on the high-field side. These results may provide a reference for future ICRF heating experiments and contribute to experimental optimization through program optimization.
