How to keep cavities blemish-free

by Rika Takahashi

Worrying about blemishes on the skin is not just an issue for people who pursue personal physical beauty, but also for accelerator scientists. Scientists and engineers at KEK have found a way to deal with unwanted stains on the inner surface of superconducting cavities, which might be one of the causes of performance limitation.
