The Relativistic Heavy Ion Collider RHIC will collide polarized proton beams up to a maximum beam energy of 250 GeV [1]. The invariant spin field in a high energy ring can vary substantially across the beam. This decreases the amount of polarization provided to experiments and makes the polarization strongly dependent on the position in phase space. This paper describes a method to compute the invariant spin field by adiabatically blowing up the beam with an rf dipole. This method will also allow measuring the invariant spin field in RHIC.
