Abstract

Tomography techniques using the two measurement arrays were investigated. To evaluate test reconstruction methods with three combinations of calculation grid and observation view lines, a model distribution was reconstructed. The two-dimensional distribution generated on a calculation grid arranged parallel to the actual apparatus view lines was in better agreement with the model distribution than the distribution generated on a square grid. This parallel grid was applied to the reconstruction of the deuterium Balmer-series lines in the JT-60U detached divertor plasmas.
