Abstract: The polarization of proton beam during the acceleration process in a particle accelerator is affected by the existence of spin resonances. Coupling spin resonances can be excited in the presence of the betatron coupling introduced by rolled quadrupoles and solenoids, as well as in when the stable direction of the spin deviates from the vertical (for instance, by partial Snakes or spin rotators). In this study, We extended the ASPIRRIN code to account for the effect of solenoid magnets and related betatron coupling on the spin resonances. The examples of the coupling spin resonance for RHIC are given. In addition, an analysis is presented for spin coupling resonances produced in the AGS due to the partial Snakes.
