چکیده

We have proposed a new method of generating highly polarized positrons through Compton scattering of polarized laser lights o! relativistic electron beams and successive pair creation. To realize high-luminosity laser}electron collisions, we constructed a specially designed chamber which equips o!-axis parabolic mirrors with a through hole at the center. This mirror achieves strong focusing of laser lights as well as head-on collisions of laser lights with e~ beams, so that the luminosity can be signi"cantly increased. A polarimeter is designed for the measurement of positron polarization. ( 2000 Elsevier Science B.V. All rights reserved. PACS: 29.27.H; 41.75.H; 42.25.J

Recent Developments in the Design of the Nlc Positron Source*

Recent developments in the design of the Next Linear Collider (NLC) positron source based on updated beam parameters are described. The unpolarized NLC positron source [1,2] consists of a dedicated 6.2 GeV S-band electron accelerator, a high-Z positron production target, a capture system and an L-band positron linac. The 1998 failure of the SLC target, which is currently under investigation, ma...

Generation of circularly polarized photons for a linear collider polarized positron source

Various methods of obtaining longitudinally polarized positrons for future linear col-liders are reviewed. Special attention is paid to the schemes using circularly polarized high-energy photons for positron production. Most effectively such photons are obtained from electrons passing through a helical undulator or colliding with a circularly polarized laser wave. Spectrum and polarization of r...

Single–pass Laser Polarization of Ultrarelativistic Positrons

The new method for producing of the polarized relativistic positrons is suggested. A beam of unpolarized positrons accelerated up to a few GeV can be polarized during a head-on collision with an intense circularly polarized lazer wave. After a multiple Compton backscattering process the initial positrons may lose a substantial part of its energy and, as consequence, may acquire the significant ...

A pr 2 00 3 Is it possible to obtain polarized positrons during multiple Compton backscattering process ?

1. In existing projects of electron-positron colliders, the option of polarized electron and positron beams is considered [1,2]. While one can consider the problem of producing the polarized electron beams with required characteristics as having been solved [3], the existing approaches to polarized positrons generation [4-7] do not provide required parameters. In quoted papers the schemes were ...
