Abstract

An algorithm for the plasma density profile reconstruction based on heavy ion beam plasma probing diagnostic data is developed. The algorithm is applied to a typical TJ-II stellarator pulse with a chord-average density varying from 0.5 × 1019 to 5.0 × 1019 m−3. The results of experimental data processing—the evolution of the reconstructed plasma density profile—are presented.
