A novel precision polarimeter will go a long way in satisfying the requirements of the precision experiments being planned for a future facility such as the Electron Ion Collider. A polarimeter based on the asymmetry in the spacial distribution of the spin light component of synchrotron radiation will make for a fine addition to the existing-conventional Møller and Compton polarimeters. The spin light polarimeter consists of a set of wriggler magnet along the beam that generate synchrotron radiation. The spacial distribution of synchrotron radiation will be measured by an ionization chamber after being collimated. The up-down spacial asymmetry in the transverse plane is used to quantify the polarization of the beam. As a part of the design process, firstly, a rough calculation was drawn out to establish the validity of such an idea. Secondly, the fringe fields of the wriggler magnet was simulated using a 2-D magnetic field simulation toolkit called Poisson Superfish, which is maintained by Los Alamos National Laboratory. This was used to account for beam motion effects and the corresponding correlations were show to be negligible. Lastly, a full fledged GEANT-4 simulation was built to study the response time of the ionization chamber. This GEANT-4 simulation was analyzed for variety of effects that may hinder precision polarimetry. It was found that a Spin-Light Polarimeter would be a fine relative polarimeter.

目前有几个建议，建立一个高光度的电子-离子对撞机，研究物质的自旋结构和测量重核中的部分子密度，并寻找胶子饱和和新的现象，如有色玻璃凝聚体。这些测量需要重核操作。我们计算了两个重要的过程，将影响加速器和检测器的操作：束缚自由对生产，和库仑激发的核的截面。这两种反应都有很大的横截面，28-56 mb，这会导致束离子损失，产生电荷质量比改变的粒子束，并在零度量热计中产生大通量的中子。射束粒子的损失将可持续的电子-离子光度限制在$10^{32}/$ cm $^2$ /s的几倍的水平。
