Feasibility of a Spin Light Polarimeter at 12 GeV JLab

ORAL

Abstract

The future 12 GeV program at JLab includes several key high precision experiments that aim to use parity violation in electro-weak interactions to search for Physics beyond the standard model. These include the ultra precise M{\o}ller experiment and the parity violating deep inelastic scattering experiment. These experiments will all rely on precision electron polarimetry with uncertainty of $\sim$ 0.4 \%. This ambitious goals can be achieved if several independent and high precision polarimeters are used simultaneously. In addition to being precise, the polarimeters must be non-destructive and must achieve the desired statistical precision in the shortest time possible. A complimentary polarimetry technique based on the spin dependence of synchrotron radiation referred to as ``spin light,'' is often overlooked. We have explored the feasibility of a spin light polarimeter at JLab for the 12 GeV era. We will present some of these results of the feasibility study and the conceptual design of a spin light polarimeter. Such a device promises to be a high precision, fast and continuous relative polarimeter. A R\&D proposal to develop a spin light polarimeter at JLab will also be discussed.
