Description
The Rapid Cycling Synchrotron (RCS) of the China Spallation Neutron Source (CSNS) is planned to upgrade its beam power from the current 100 kW to 500 kW in the CSNS-II phase. However, significant beam-intensity-dependent transverse instability has already been observed during routine 100 kW operation. As the beam power increases further, this instability is expected to become much stronger. To effectively suppress the coherent transverse oscillations induced by impedance wakefields and injection errors, a bunch-by-bunch transverse feedback system is essential. This paper evaluates the performance of the digital filter and the complete bunch-by-bunch feedback chain, from the front-end electronics through the power amplifier to the strip-line kicker. Feedback system simulations are performed to optimize key parameters, providing critical guidance for the design, commissioning, and future operation of the system.
