Superconducting Radio Frequency Technology: Expanding the Horizons of Physics and Technology

摘要

Superconducting radio frequency (SRF) accelerating structures promise low rf losses and high gradients under continuous wave operation. High-quality, intense continuous wave beams can be accelerated without risk of melting the structure and without requiring enormous amounts of input rf power. The intrinsically low losses make SRF technology attractive for high-energy electron-positron storage rings and colliders, TeV-scale electron-positron linear colliders, free electron laser drivers, and all types of cw linacs. Progress in SRF technology is reviewed and some present and proposed SRF accelerator projects are described. Cryogenic temperature optimization is also briefly discussed.
