Closed orbit instability
2001
Physical Review Special Topics. Accelerators and Beams
Preserved Fulltext
Due to a long-range resistive wake, the closed orbit in high-intensity circular accelerators may experience an unstable drift. Unlike the conventional betatron instabilities, this closed orbit instability is not sensitive to the spread of the betatron frequencies. For bunched beams, feedback appears to be the only way to stabilize the closed orbit above threshold. This new instability can be significant for long, high intensity rings.
