The authors studied the acceleration of a spin-polarized beam through a depolarizing resonance using a partial Siberian snake. They accelerated polarized protons from 95 to 140 MeV while ramping a 10% partial Siberian snake along with the acceleration cycle. The 10% partial snake suppressed all observable depolarization during acceleration due to the G{gamma}=2 imperfection depolarizing resonance which occurred near 108 MeV. However, 20% and 30% partial Siberian snakes apparently moved an intrinsic depolarization resonance, normally near 177 MeV, into this energy range; this caused some interesting but not-yet-fully understood depolarization.
