Polarized 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...
متن کاملPolarized Electron Sources for Linear Colliders ”
A&TRACT Linear colliders require high peak current beams with low duty factors. Several methods to produce polarized e’ beams-for accelerators have been developed. The SLC, the first linear collider, utilizes a photocathode gun with a GaAs cathode. Although photocathode sources are probably the only er@ical alternative for the next generation of linear colliders, several problems remain to be s...
متن کاملHighly Polarized Electron Beams for Linear
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 pol...
متن کاملLaser cooling of electron beams at linear colliders . ∗
A method of electron beam cooling is considered which can be used for linear colliders. The electron beam is cooled during collision with focused powerful laser pulse. The ultimate transverse emittances are much below those achievable by other methods. This method is especially useful for high energy gamma-gamma colliders. In this paper we review and analyse limitations in this method, also dis...
متن کاملChallenge of polarized beams at future colliders
A short overview about the potential of polarized beams at future colliders is given. In particular the baseline design for polarized beams at the ILC is presented and the physics case for polarized e and e is discussed. In order to fulfil the precision requirements spin tracking from the source to the interaction point is needed. Updates concerning the theoretical calculations as well as their...
