description: The given work is devoted to researching on solvability of poloidal rotation task and finding out structure with highest level of recovered solution accuracy. The research set the following goals: 1. Introductory processing of the data - formation of model solutions, vectors of free coefficients and detector images. 2. Recovery of solution with various methods. 3. Development of objectâs configuration which solution is recovered with the best accuracy. 4. Implementation of object rotation and predicting the potential way of this task and the extension on evolutionary formulations of the poloidal problem. This work was carried out with information received from the tokamak âGlobus-M2â, located in FTI named on A.F. Ioffe. The mosaic detector, collecting data on a low angle tomography, is included as the part of the tokamak. The significant complexities bounded with a low angle tomography are bad conditionality of the source data and ambiguity of solutions. For such tasks interval analysis, in particular, subdifferential Newton method, is used. The study resulted into defining the optimal trapezoidal configuration of the luminous object, recovered with better precision, using spectral analysis; also rotation of this object was realized. There were developed recommendations on selection of the study object and methods potentially effective in solving tasks of plasma evolution.
