Abstract :
Accurate plasma boundary information is essential for Tokamak runtime control, yet unable to be directly obtained due to super-high temperature. Based on improved B-Snake model, we proposed a new plasma boundary reconstruction algorithm. The contour energy, boundary flux, initial boundary, and algorithm flow were introduced. By mapping flux distribution into flux image, the model output plasma shape. Experiments showed its favorable boundary accuracy and deduced parameters for shape control purpose.
