Scientists from the Russian State Atomic Energy Corporation (Rosatom) have invented a new method for manufacturing superconductors. They proposed an accelerated process - a method combining magnetron sputtering with subsequent crystallization.

The enterprise publication "Rosatom National" reported: "At the Bichvarev Institute, technical upgrading for producing high-temperature superconductors VTSP-2 has been completed, and the related plan aims to apply future energy equipment on a large scale."

Currently, the most commonly used technology for depositing VTSP-2 superconducting layers is laser ablation: a laser beam is used to irradiate ceramic targets containing gadolinium or yttrium, barium, and copper, and the melted material is deposited on a strip substrate. However, "Rosatom National" pointed out: "This method is time-consuming and expensive."

However, Russian scientists proposed another solution.

Daria Novosilova, head of the High-Temperature Superconductivity Laboratory at the Bichvarev Institute, said: "We hope that the method combining magnetron sputtering with subsequent crystallization can speed up the production process. This technology has been studied for many years, and the new phase plan involves preparing oxide ceramic superconducting layers on strip substrates using new equipment."

According to "Rosatom National", the institute has purchased rolling mills and supporting equipment for manufacturing metal strip substrates, and now scientists can produce strip materials and superconductors simultaneously.

Superconductors are widely used in medical (magnetic resonance imaging scanners), transportation (magnetic levitation trains), energy (lossless power transmission lines, transformers, current limiters), scientific research (particle accelerators, nuclear fusion tokamaks, radio telescopes), and high-end electronics (quantum computers, Josephson junctions, SQUIDs for ultra-fine magnetic field measurements). In defense industry, superconductors are used in electromagnetic pulse systems and submarine silent engines; in aerospace technology, they are used in infrared detector cooling and energy storage systems for telescopes.
