Weight optimization of a coil of the electromagnetic system of the TB-O device

To optimize the magnet coil designs for large tokamaks, the optimum coil configuration is calculated. The coil is modelled as a flat curved bar of small curvature with the reduced rigidity characteristics, which is loaded with ponderomotive forces. The accepted mathematical model permits to formulate the optimization problem already at the designing stage and so to reasonably choose the design parameters. The optimization effects for a curved bar are attained by redistributing the curvature radius, the radius size being restricted by some design factors. The optimum outlines of a curved bar are calculated. The calculations confirm the validity of the technique suggested
