  The physics program at the upgraded Jefferson Lab (JLab) and the physics
program envisioned for the proposed electron-ion collider (EIC) include large
efforts to search for interactions beyond the Standard Model (SM) using parity
violation in electroweak interactions. These experiments require precision
electron polarimetry with an uncertainty of $<$ 0.5 %. The spin dependent
Synchrotron radiation, called "spin-light," can be used to monitor the electron
beam polarization. In this article we develop a conceptual design for a
"spin-light" polarimeter that can be used at a high intensity, multi-GeV
electron accelerator. We have also built a Geant4 based simulation for a
prototype device and report some of the results from these simulations.
