Abstract:
In order to cure the transverse coupled-bunch instabilities of BEPCⅡ and improve the beam current of the rings, a prototype of transverse bunch-by-bunch feedback system was studied and made. The experiment of this prototype on the BEPC storage ring shows that this system can work well. The beam instabilities can be successfully suppressed when the feedback loop is closed. This paper describes the prototype of the transverse feedback system and the preliminary test results.
