Abstract: We explore the potential for extracting the longitudinal proton structure function FL at the future Electron Ion Collider (EIC) through a Rosenbluth separation method. The impacts of differing assumptions on sample sizes, systematic uncertainties, and beam energy scenarios are investigated. With a sufficiently large number of center-of-mass energy configurations and well-controlled systematics, the EIC will measure FL to an unprecedented precision, even with relatively modest luminosities. The accessible kinematic range complements both fixed-target and Hadron-Electron Ring Accelerator data. In the most optimistic scenarios, the EIC data will be a highly competitive direct probe of the proton gluon density.
