Algorithm for reconstruction of the shape of the plasma column cross section in the KMT facility

Algorithm for reconstruction of the shape of the plasma column cross section in the Kazakhstan Tokamak for Material Testing (KTM) based on the method of elementary ring current filaments is described. Based on the suggested algorithm, the program Plasma_Shape_Reconstructor has been developed for calculation and visualization of the plasma parameters based on the vector of input parameters measured by electromagnetic diagnostics sensors of the tokamak. The correctness of the reconstructed plasma column shape, position of the X -point, and internal magnetic surface is estimated, and the series of program tests is performed to determine the time of algorithm execution and the stability of the reconstruction process.
