  A novel polarimeter based on the asymmetry in the spacial distribution of
synchrotron radiation will make for a fine addition to the existing M{\o}ller
and Compton polarimeters. The spin light polarimeter consists of a set of
wiggler magnet along the beam that generate synchrotron radiation. The spacial
distribution of synchrotron radiation will be measured by ionization chambers.
The up-down (below and above the wiggle) spacial 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.
