Abstract
We have measured the time dependence. of the polarization of a stored proton beam near an intrinsic depolarizing resonance. The distance to the resonance was varied by changing the vertical tune of the storage ring. The measurements are consistent with exponential decay and with a simple model for the change of the lifetime as the resonance is appr oached. It was originally expected that the presence of an internal ta rget stimulates depolarization: however, we found no evidence for such an effect.
