Abstract
Stochastic cooling, based on a feedback system, aims at damping the oscillation of particles. Stochastic cooling is more suitable to cool secondary beam with larger size and momentum spread, and it is therefore can be complemented with electron cooling, in order to obtain beam of higher quality. Stochastic cooling system is being designed and constructed on the experimental Cooling Storage Ring of HIRFL. By simulation of Betatron stochastic cooling, it is obtained that the importance for shortening the cooling time and reducing cooling equilibrium by improving bandwidth, increasing the numbers of pickup and kicker, and decreasing the system noises. Meanwhile, the heating during the cooling process caused by larger momentum spread or larger gain of amplifier is analyzed.
