Polarized Beams in High-Energy e+e- Storage Rings

  • Bryan W. Montague


The polarization of electron/positron beams in storage rings is fundamentally governed by the quantized nature of synchrotron radiation. On the one hand, beams can become polarized by the Sokolov-Ternov spin-flip asymmetry of the photon emission, whereas on the other hand, the abrupt energy loss excites orbit oscillations which perturb the spin motion and give rise to depolarizing effects. It is the balance between these two aspects of the same phenomenon that determines the degree of beam polarization that can be built up and maintained in a machine.
