Abstract :
We have proposed a new method of generating highly polarized positrons through Compton scattering of polarized laser lights off relativistic electron beams and successive pair creation. To realize high-luminosity laser–electron collisions, we constructed a specially designed chamber which equips off-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 significantly increased. A polarimeter is designed for the measurement of positron polarization.
