抄録

We have been pursuing a basic study of a polarized positron source for a next generation linear collider, JLC based on two fundamental processes, i.e. inverse Compton scattering of circularly polarized laser-photons and pair-creation of a polarized y-ray. Polarized y-rays were produced at collisions of circularly polarized laser-beams with a wave length of 532nm provided from a Nd: YAG with counterpropagating electron beams of 1.28 GeV. Since a time-duration of produced γ -rays is extremely short, i.e. 30 ps, we have developed a transmission method in which a total flux of γ-rays passing through magnetized iron is measured resulting in asymmetry determination. We will report technical details of a positron polarimetry, which will be soon employed to substantiate our proposed view concerning a JLC polarized positron source.
