The Electron-Ion Collider: Assessing the Energy Dependence of Key Measurements.

We provide an assessment of the energy dependence of key measurements within the scope of the
 machine parameters for a U.S. based Electron-Ion Collider (EIC) outlined in the EIC White Paper.
 We rst examine the importance of the physics underlying these measurements in the context of the
 outstanding questions in nuclear science. We then demonstrate, through detailed simulations of the
 measurements, that the likelihood of transformational scientic insights is greatly enhanced by making
 the energy range and reach of the EIC as large as practically feasible.
