The problem of accelerating polarized protons to high energies is sync
hrotrons is considered. The Siberian snake method is applied to preser
ve beam polarization during acceleration in synchrotrons. The practica
l realization of this method is considered. An estimate is obtained of
the number of snakes required in an accelerator for preserving beam p
olarization. The influence of the Siberian snakes on beam dynamics is
analyzed. The suggested method of calculating practical snake schemes
allows one to obtain appropriate snake configurations with conventiona
l or helical dipoles for a particular accelerator.
