Microwave Instability in the USSR Synchrotron Radiation Source under Design

Abstract

Investigation of instabilities that emerge in the interaction of a charged-particle beam with elements of the chamber of state-of-the-art synchrotron radiation sources and colliders is an important task, since the beam parameters required in such facilities can only be attained if such effects are taken into account. Conditions for the development of a microwave instability in the USSR, a fourth-generation 6-GeV synchrotron radiation source with an emittance of 70 pm under design, are analyzed. The options to reduce its effect on the parameters of the beam accumulated in the accelerator ring and, as a result, on the output parameters of the facility are investigated.
