Description
In the J-PARC 3-GeV rapid cycling synchrotron, second-order random resonances are excited by shifting the operating point to a higher tune side. To mitigate resonance-induced beam loss and further enhance tunability of the operating point, we studied the compensation of second-order resonances. By controlling the timing when the beam approaches resonance through adjusting the momentum offset and chromaticity-induced tune shift, the optimal resonance compensation is explored, considering the time dependence of lattice imperfections that drive the resonances. The analysis of resonance driving terms and numerical simulation was employed to deepen the understanding of the lattice imperfections. In this article, details of the method and experimental results will be reported.
