Description
We study a single RF ramp for the Rapid Cycling Synchrotron (RCS) of the Electron–Ion Collider (EIC) that can cover the full energy range from injection to extraction without changing individual cavity gradients. To reach the required vector sum voltage at each moment while keeping both RF systems at their maximum gradient, we operate the two systems out of phase. We show how this approach preserves bucket area and longitudinal matching, while keeping cavity operation simple. Simulations indicate that it can maintain good capture efficiency and longitudinal stability. We also discuss practical aspects, such as phase control and low-level RF requirements.
