Highly Polarized Electron Beams for Linear
نویسنده
چکیده
Work supported by Department of Energy contract DE{AC03{76SF00515. The SLC operates with electron beams having a polarization of 80%. The physics opportunities for future colliders will be greatly enhanced if the beam polarization can be signicantly higher. The prospects for achieving electron single-beam polarizations 95% are discussed. A complimentary achievement w ould be to use two-beam polarization.

متن کاملPolarized electron beams for linear colliders*
Longitudinally polarized electron beams for high energy collisions provide a sensitive way to explore the electroweak process as well as an effective means to measure spin dependent properties of particles. Once created, such beams are readily accelerated by linacs without loss of polarization, although emittance damping rings present potential hazards. The essential elements of a collider nece...
