Spin Light Polarimeter for the EIC
ORAL
Abstract
We plan to develop a realistic design for a novel polarimeter which will go a long way in satisfying the requirements of the precision experiments envisioned for the Electron Ion Collider (EIC). The Spin Light polarimeter is foreseen to be a non-invasive and continuous beam diagnostic instrument. 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 conventional M\"oller 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. As a part of the design process, simulation of the effects of fringe field of the 3-pole wriggler magnet that forms the primary component of the polarimeter is underway. The fringe field was simulated using LANL Poisson Superfish mesh EM solver. The results from the beam motion studies, the preliminary design parameters of the polarimeter and GEANT4 simulation of the ionization chamber will be discussed.
