A facility is described that allows generation of long current pulses with a virtually constant amplitude by a superconducting inductive (magnetic) energy storage with a 5-MJ energy content. The design of this facility ensures the possibility of changing the parameters of an output current pulse by varying the inductances of the magnetic-system's sections and their electromagnet coupling. This approach allows not only the stabilization of the current pulse but also a severalfold increase in the initial current value. The electric insulation of the storage's coil can withstand a voltage higher than 200 kV, and a special system of multielectrode current leads can transfer a power of up to 250 MW at a 1.3-kA current from the cold zone (4.2 K) into the warm (300 K) zone almost without energy losses. The current can be increased to 10 kA by changing the connection of the facility's sections. The facility has been tested in six full-scale experiments and is ready for further tests as a component of electrophysical facilities of various purposes.
