Present state of the problem of high-current technological superconductivity

Review of some directions of technical application of high-current superconductivity in the course of developing new technique samples in industrial physics, electric power engineering and in other fields is given. Technological superconducting materials most perspective for creating superconducting magnetic systems (SMS) are presented. It is shown that only SMS creation allows one to possess accelerators with 0.8-20 TeV proton energy, construct tokamak devices, perform thermonuclear investigation with magnetic plasma confinement (open traps). In the last decades SMS are used in magnetic separation processes-experimental and experimental-commercial samples of separators with SMS are developed in a number of countries and they are now udergoing commercial tests. Application of magnetic resonance (MR) tomography method in medical diagnostics appears to be a perspective direction. When creating MR-tomographs extremely high requirements concerning space homogeneity of magnetic field are placed, which may be secured only by SMS application
