Abstract

Li-CXS (fast lithium-beam-activated charge exchange spectroscopy) is applied for measuring spatially and temporally resolved impurity ion concentrations in the TEXTOR tokamak edge plasma. After a brief description of the method of Li-CXS and its capabilities, a model is presented for attenuation and atomic state population of an injected Li beam due to collisional interactions with the background plasma particles, taking into account up to eight excited LiI states in the stepwise excitation-ionisation processes. Measured impurity radiation characteristics resulting from Li-activated CX of C(q+) (q=5,6) in ohmically heated TEXTOR plasmas are evaluated with this model and lead to the corresponding impurity ion concentrations within the TEXTOR edge region.
