Superconductive Conductors

220

tonnes

of superconductive strands supplied under the ITER project

Superconductors based on niobium-titanium and niobium-tin are used in fundamental science projects, in the creation of modern medical equipment (e.g., magnetic resonance tomographs), transportation and industrial sectors, as well as in high- and ultra-high-resolution analytical equipment, such as nuclear magnetic resonance spectrometers.

It is a composite wire (strand) of 0.5-2.0 mm in diameter and up to 50 km in length, which contains up to several tens of thousands of continuous superconductive fibers in a metal matrix, each of 1.5-5 microns in diameter. Superconductive materials are subject to high technical specifications for the magnitude and stability of critical parameter values, structural homogeneity along the length, tolerances on geometric dimensions of the cross-section, level of current characteristics, etc.

The only Russian manufacturer of a full cycle of low-temperature superconductors is Rosatom's Fuel Company TVEL. Industry projects on superconductive materials are managed by Rusatom Metal Tech LLC; scientific research, development of superconductive strand designs and manufacturing processes are performed by VNIINM JSC in Moscow; and commercial production is realized at the production site of Chepetsky Mechanical Plant JSC in Glazov.

Superconductive Strands for Scientific Installations

The properties of a superconductor cooled to the temperature of liquid helium (269°C below zero) allow high magnetic fields up to 12 Tesla. The strands are used in high-powered accelerating installations, used to conduct scientific research in high-energy physics, quantum physics, and elementary particle physics. For example, for accelerating and fusion installations, and high-energy physics of such megascience projects, like ITER, FCC, NICA, FAIR, etc.

Superconductors for Medical Installations

Modern tomographs use superconductive conductors to generate a constant magnetic field. Due to the effect of superconductivity, i.e. lack of resistance, electric current circulates in the winding almost infinitely, thus generating a constant magnetic field. Furthermore, superconductors allow to increase the magnetic field of the tomograph, improving the resolution of the images and the quality of diagnostics.

Superconductors for High-Field Magnets

High electromagnetic fields need be created in scientific installations to study properties and parameters of various materials. For this purpose, the use of superconductors allowed to reduce mass and size characteristics of laboratory installations many times over, thereby expanding their functional capabilities and increasing their scope of application. Rosatom's Fuel Company TVEL has been qualified as a supplier of superconductors for the programs of developing high-field magnets for particle accelerators of the Future Circular Collider (FCC) project. A qualifying batch of niobium-tin superconductive wires with a total length of 50 km was manufactured at Chepetsky Mechanical Plant JSC in Glazov, while the production design and process for the strands were developed at VNIINM JSC.

Superconductors for Quantum Computers

The development of artificial intelligence and new information technologies is inextricably linked to the development of quantum computers. Stable operation of a quantum computer requires very low temperature (hundredths of kelvin above zero), and high-speed lossfree transmission of information requires superconductive coaxial cables, which have low thermal conductivity and no electrical resistance.

Rolled Products Made of High-Purity Niobium

Chepetsky Mechanical Plant JSC has developed an import-substituting technology for the production of high-purity niobium sheets. This material is used as a basis for manufacturing superconductive resonators, the devices that create an electric field to accelerate charged elementary particles: protons, ions, and electrons. Particle accelerators are the main tools of scientists in modern experimental physics. Technologies based on superconductive resonators are the basis for research facilities of the largest megascience research projects.
