superconducting radiofrequency

Superconducting radiofrequency (SRF) involves the use of superconducting materials—metals that conduct electricity without resistance when cooled to very low temperatures—to generate and control high-frequency electromagnetic fields. These fields accelerate particles, such as electrons or protons, in applications like particle accelerators. Because superconductors have no electrical resistance, SRF cavities can efficiently produce strong accelerative fields with minimal energy loss, enabling high-performance, cost-effective operation essential for scientific research and medical technologies.
