Techniques for Longitudinal Polarization in Electron Storage Rings


Progress in studies for designing polarized beams in very high energy electron storage rings is reviewed. Main emphasis is concentrated on devices delivering special spin manipulations for obtaining highly and longitudinally polarized electrons of both helicities at interaction points in collision mode with opposite beams of positrons (or protons). These devices are: 90° spin rotators, 180° spin rotators (Siberian snakes), asymmetric wigglers, spin flippers and finally spin matching procedures for suppressing beam-beam depolarization. Recent theoretical progress allows now experimental developments at future high energy electron rings like HERA, TRISTAN and LEP.
