Description

The Electron Ion Collider (EIC) will make precision measurements of different asymmetries to shed light on nucleon structure and dynamics. One of the most important sources of systematic uncertainty is the determination of the degree of polarization of the electron beam. This talk will detail the challenges to electron polarimetry in this new machine and the current status for the Compton polarimeter. The focus will be on two aspects: the laser system and the detector package. The designed laser system will make use of different advances in the field to decrease systematics and increase radiation hardness of the system. The detection system will need to measure both a positional asymmetry and an energy asymmetry to fully disentable the polarization direction.
