Design of the magnet system for neutron yield zone of the plasma neutron source based on the gas-dynamic trap

In the report the results are presented on design and computation of the el ectromagnet system of neutron yield zone for four cases: 18, 20, 22 and 25 T field strength in the optimized mirror magnet. Special optimization techn ique was used for optimization of the mirror magnet. For 25T field strength the neutron emission zone has maximum dimensions and parameters, but consu mption power of resistive coils is 0,7 divided by 0,5 MW. The use of an up- to-date superconductor for high field makes it possible to design the 18, 2 0, 22T electromagnet system made only from the superconductor. The superconductor parameters required to achieve 25T field on the axis of the mirror magnet, made entirely from a superconductor, are presented.
