    "abstract": "Aim of this paper is to present a brief and basic introduction to polarized\nbeams and the behaviour of a particle\u0027s spin in an electromagnetic field. It is\nnot intended to give a complete presentation of the spin dynamic theory.\nInstead the most importa nt features are given without proof and details not\nabsolutely necessary are left out. Spin depolarizing mechanisms are discussed\nand the cures against depolarizing especially during acceleration as utilized\nat COSY are outlined. A list of references is given at the end to help the\nreader to find more deep details on spin dynamic theory [1].",
