Abstract :
A bunch by bunch transverse feedback system, as a complement of the longitudinal feedback system required for the suppression of the coupled bunch beam instabilities, has been developed and undergoing testing in the PLS. Major components are two beam oscillation detectors, betatron phase adjuster, notch filters and a stripline kicker. Each system component and its functions are described with simple trigonometric calculations. Preliminary result of the beam test has shown 30 dB damping of the beam oscillation
