Problem
Compact magnetic fusion reactors require strong magnetic fields for plasma confinement, but conventional conductors cannot efficiently generate these fields at elevated temperatures. This limitation hinders the development of economically sustainable fusion energy and other applications requiring high magnetic fields.
Solution
Suprema develops high-temperature superconducting (HTS) tapes that enable the creation of strong magnetic fields necessary for advanced applications, including compact magnetic fusion reactors. Their HTS tapes leverage REBCO (Rare Earth Barium Copper Oxide) superconducting material, allowing operation at higher temperatures than traditional superconductors while carrying significantly higher electric currents in strong magnetic fields. By focusing on industrial scalability and proprietary equipment design, Suprema aims to meet the increasing demand for HTS tapes in energy, mobility, biomedical, and scientific research sectors. The tapes are manufactured using physical vapor deposition techniques, with a strategic focus on Pulsed Laser Deposition (PLD) for the superconducting layer, ensuring high-quality and uniform production.
Target Audience
The primary customers are developers of compact magnetic fusion reactors, power grid infrastructure, electric motors, scientific research equipment, and other applications requiring high-performance superconducting materials.
