Technique for charged particle beam instability suppression

A method for suppressing instability of a charged particle beam resulting from its interaction with accelerating cavities in ring accelerators and storages in the circulation mode is suggested. The method comes about as follows. The eigenfrequencies of the cavities are so changed over a range exceeding the cavity pass band that time of passage of cavity pass band with respect to the frequencies multiple to the beam rotation frequency is less than the time of instability development
