      abstract     = {Accelerating a polarized beam in a synchrotron requires the
                      highest possible superperiodicity of the lattice in order to
                      minimize the number of depolarizing intrinsic resonances.
                      However, at the cooler synchrotron COSY the standard lattice
                      to accelerate the beam to maximum momentum has a reduced
                      superperiodicity since the harmful transition energy is
                      shifted upwards during acceleration. This procedure allows
                      internal experiments to take data in the whole acceleration
                      ramp. Unfortunately the reduced superperiodicity excites
                      additional intrinsic resonances. To solve this contrary
                      situation a modified beam optics was found which
                      significantly lowers the strength of these intrinsic
                      resonances. Measurements confirming this theoretical concept
                      are presented.},
