Abstract :
The paper describes the bunch by bunch transverse feedback system developed and implemented at SOLEIL. In order to cope with diverse beam conditions involving multibunch and single bunch instabilities, a digital system has been developed. While a BPM, a RF frontend and a stripline developed in house are used in the feedback chain, the SPring-8 solution was chosen for the digital processor for its proven performance elsewhere. The commissioning of the system as well as attained feedback performance is presented.
