Estimate of the Possibility to Reduce the Mechanical Stresses in the Central Region of the Magnetic System of a Tokamak

Modern trends in tokamak design include the use of strong magnetic fields, whose generation produces Lorentz forces, which can damage the electromagnetic system (EMS) of the tokamak. A concept for the tokamak EMS is proposed that ensures reduced loads in the central region. Results of numerical simulations are presented, which substantiate the possibility of a significant reduction in mechanical stresses on the tokamak inductor through the use of quasi-force-free windings.
