An Overview of the sPHENIX Event Plane Detector

The volume and shape of quark gluon plasma produced in heavy-ion collisions at the Relativistic Heavy Ion Collier are correlated with the final state particles and are defined by the centrality and event plane. One system providing the capability to determine the centrality and event plane of collisions at the sPHENIX detector will be the Event Plane Detector (sEPD). The sEPD will consist of two segmented disks of scintillating plastic covering a pseudorapidity of 2.0 to 4.9. In this talk, the expected operation and performance of the sEPD will be outlined. A case for measuring centrality and the event plane in the forward region will be presented. Additionally, select planned measurements to be made at sPHENIX utilizing the sEPD will be discussed.
