Abstract
As the stored beam current increases over 240 mA, transverse coupled-beam i nstability limits higher beam current in Pohang Light Source. A bunch by bu nch transverse feedback system has been developed to cure these beam instab ilities. It consists of beam oscillation detectors, betatron phase adjuster , power amplifiers and a stripline kicker. Design of each circuit and its f unctions are described with simple trigonometric equations. The result of t he beam test has shown more than 30 dB damping of the beam oscillation in t he full bandwidth of the system. (C) 2001 Elsevier Science B.V. All rights reserved.
