Synchrotron radiation has been used for many years as a beam diagnostic tool at electron accelerators. It allows measurements of the transverse and longitudinal polarization, spatial distribution and bunch structure of the beam, as well as the absolute value of the beam energy and its distribution. The electron spin dependence of the synchrotron radiation called spin light has a spatial asymmetry which can be exploited to measure the beam polarization. The magnified angular distribution of the visible portion of the synchrotron spectrum can be used for a non-destructive measurement of the beam energy with high precision. We will present the conceptual design of a spin light polarimeter and a beam energy measurement scheme for multi-GeV electron beams and we will discuss prospects of using these methods at the CEBAF accelerator at Jefferson Lab.
