The authors plan to install in the IUCF Cooler Ring a rampable partial (30%) Siberian snake to test if the spin polarization is preserved during adiabatic turn-on. They also plan to use this ramped snake to accelerate polarized protons to 370 MeV while passing through two depolarizing resonances. The Siberian snake will consist of two small rampable warm solenoids placed symmetrically on either side of the exciting cold 2 T{center_dot}m solenoid which would run dc at about 0.5 T{center_dot}m. Ramping each warm magnet from about {minus}0.25T{center_dot}m to + 0.25 T{center_dot}m. Recent experiments showed that turning on the snake in 100 msec at 370 MeV causes no serious beam loss.
