  The nuclear modification factors R_{AA} and R_{CP} have been used to measure
medium-induced suppression in heavy-ion collisions at sqrt{s_{NN}} = 200GeV
which was among the earliest evidence for the existence of a strongly
interacting medium called a quark-gluon plasma (QGP). Nuclear modification
factors for asymmetric collisions (R_{dA}) have measured the Cronin Effect, an
enhancement of high transverse momentum particle yields in deuteron-gold
collisions relative to proton-proton collisions. A similar enhancement is
observed in data presented in these proceedings and competes with the quenching
caused by partonic energy loss in the QGP. In these proceedings we will present
charged-hadron R_{CP} at mid-rapidity for sqrt{s_{NN}} = 7.7 - 62.4GeV as well
as identified pi^{+}, K^{+}, and proton R_{CP}. Comparisons to HIJING motivate
possible methods for disentangling competing modifications to nuclear
transverse momentum spectra.
