Description

The soft X-ray imaging system on HT-7 is introduced. Fourier-Bessel expansion method is used to reconstruct the soft X-ray emission distribution. Simulation results show that the inversion accuracy is associated with the angular expansion limit and the hot core displacement. In addition, tomographic results of sawtooth oscillations in a typical low hybrid current drive (LHCD) plasma are presented. It is shown that the reconstructions are reliable to analyze the perturbative mode and the evolution. (magnetically confined plasma)
