A novel polarimeter based on the asymmetry in the spatial distribution of synchrotron radiation (SR) will make for a fine addition to the existing Møller and Compton polarimeters. The spin light polarimeter consists of a set of wiggler magnet along the beam that generate synchrotron radiation. The spatial distribution of synchrotron radiation will be measured by ionization chambers. The up-down (below and above the wiggle) spatial asymmetry in the transverse plain is used to quantify the polarization of the beam. As a part of the design process, effects of a realistic wiggler magnetic field and an extended beam size were studied. The perturbation introduced by these effects was found to be negligible. Lastly, a full fledged GEANT-4 simulation was built to study the response of the ionization chamber (IC).
