Optimization of the magnet mirror for neutron source based on the GDT-concept

Proposals for the designing of a combined magnet system for a steady-state magnetic field with 26 T induction in the center of a 90-mm-diameter opening are presented in the paper. The algorithms, based on the Lagrange optimization method, for the superconducting solenoid minimization in the superconductor volume and those for the resistive solenoid in consumed active power are given. The results of the eleetromagnetic calculations for two options of the resistive solenoid design at an equal stack coefficient of conductor filling are presented.
