Superconducting film technology leads to record performance for low-frequency SRF cavity

Superconducting radio-frequency (SRF) cavities are the “muscle” of many modern particle accelerators. By cooling these devices to cryogenic temperatures (usually around 2 Kelvin, or minus 456 degrees Fahrenheit) and inputting electric power, SRF cavities increase the energy of beams of charged particles passing through them. Making cavities out of superconducting materials dramatically increases their efficiency […]
