Abstract
The behavior of ‘‘overlapping’’ depolarizing resonances was studied using a stored 106.4-MeV polarized proton beam. We used an rf solenoid magnet to create an ‘‘rf induced’’ depolarizing resonance which was then forced to overlap with the Gγ=2 imperfection depolarizing resonance. We found significant interactions between the two resonances by varying their frequencies and strengths; the frequency of the rf resonance strongly affected the response of the imperfection resonance to correction magnetic fields. The Siberian snake overcame all observable depolarization due to the overlapping resonances and maintained full polarization for all observed frequencies and strengths.Keywords
