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.


From CERN Bulletin: In conversation with Nobel Laureate Jack Steinberger

Awarded the 1988 Nobel Prize for Physics for his discovery of the muon neutrino, Jack Steinberger recently celebrated his 90th birthday and can still be found in his CERN office on an almost daily basis. If you happened to have a coffee with him… this is what he would tell you: his recollections, and thoughts about the present and future of particle physics.
