摘要：
This study analyzes the feasibility of a new method for monitoring the three-dimensional (3D) shape of an asymmetrically magnetized high-temperature toroidal plasma. The proposed method utilizes multiple pinholes on a single disk. Devoid of any assumptions on the plasma shape, 3D tomography images of T-e and n(e) can be successfully created using mathematical methods based on an expansion of the Fourier-Bessel series and a regression analysis on the dataset of the multiple soft X-ray filaments in numerical experiments.
