Abstract
We have proposed a new method of generating highly polarized positrons thro ugh Compton scattering of polarized laser lights off relativistic electron beams and successive pair creation. To realize high-luminosity laser-electr on collisions, we constructed a specially designed chamber which equips off -axis parabolic mirrors with a through hole at the center, This mirror achi eves strong focusing of laser lights as well as head-on collisions of laser lights with e(-) beams, so that the luminosity can be significantly increa sed. A polarimeter is designed for the measurement of positron polarization . (C) 2000 Elsevier Science B.V. All rights reserved.
