Abstract

Modelling of hydrogen line profiles in the ITER divertor plasma entails several challenges. Because of the high density (N_e > 10 ¹⁴cm^-3) and low temperature (kT_e < 2eV) expected in the magnetized plasma close to the wall, both Stark broadening and Zeeman splitting have to be taken into account in line shape calculations, [1]. Moreover, the conditions are such that the ion dynamics has to be retained in Stark broadening calculations, and the presence of a high magnetic field (B ∼ 5T) introduces couplings between Stark and Zeeman effects, which can significantly alter the profile [2, 3]. We present here Balmer lines obtained by numerical simulations based on a standard Molecular Dynamics technique, of the plasma in an external magnetic field. The simulated profiles are compared to experimental ones obtained in Plasma Surface Interaction (PSI) experiments which are carried out on Pilot-PSI of FOM.
