FIELD: electricity. ^ SUBSTANCE: method is based on generation of plasma flow in gas medium and its action at solid-state target, at the same time cumulative plasma jet is generated as focused by magnetic field in pulse mode with speed of jet outflow (4-10)105 m/sec with provision of jet pressure at solid-state target in pulse of 105-106 atmospheres with temperature of more than 106C and density of energy flow in plasma jet of 108-1010 W/cm2. As solid-state target is exposed to plasma flow, shock wave is developed in it, and energy of shock wave is sent through a layer of viscous medium to superconducting material. Plasma jet is generated in the medium of neon, argon or hydrogen, or nitrogen, or their mixture. Duration of pulse action of cumulative jet at solid-state target makes (5-10)10-8 sec. As solid-state target, a plate of refractory material is used, and viscous medium is represented by epoxide resin without hardener or other viscous material with low pressure of saturated vapours. ^ EFFECT: increased critical current in superconductor. ^ 5 cl, 2 dwg |
