Abstract :
Siberian snakes avoid crossing depolarizing resonances in circular accelerators by forcing the spin tune to half integer independent of beam energy. This concept has been proposed by Ya.S. Derbenev and A.M. Kondratenko in 1974. If only one Siberian snake is used, the invariant spin axis is in the horizontal plane. This is an interesting feature to deliver longitudinally polarized beam to internal experiments. In this papers possibilities for spin preparation at the cooler synchrotron COSY are discussed
