High magnetic fields systems is widely used in fundamental and applied research in variuos branches of science and industry. The most famous examples of such magnetic systems are tokomaks, stellators, superconducting magnets, CERN collider, ITER reactor, levitation systems. The key component of magnetic systems is inductor (solenoid). At this moment, the record magnetic fields reaches 100 T. The creation of a strong magnetic field is no longer enough just to improve designs for inductor (solenoid). Traditional electrotechnical materials and conductors can no longer withstand the huge mechanical and thermal loads, therefore, them changes to an entirely new advanced materials, for example Cu-Nb microcomposite conductors. These materials are characterized by a unique structure, excellent mechanical properties and good electrical conductivity. One of the most important and unresolved problems of high magnetic fields systems are reliable non-destructive joints and joining technologies creation. This paper reviews the strong magnetic fields systems design features, Cu-Nb conductors characteristics and structure, microcomposite conductor production specifics, application fields, joining problems and the available joining technologies.
