Jefferson Lab is proposing the construction of an Electron Ion Collider (JLEIC) that will be used to study the propagation of partons produced in nuclear matter and to search for evidence of parton saturation at low longitudinal momentum fraction x. By using geometry tagging we can enhance measurements made by particle detectors in JLEIC. Geometry Tagging is an analysis technique that uses information from the breakup of a collision to categorize the collision's geometry. This technique allows us to select event samples in a way that we can control the geometry of collision. We first focused on measuring the production of forward neutrons and then demonstrated that resolution can be improved if other forward fragments are observed.
