The Muon g-2 experiment aims to measure the anomalous magnetic moment of the muon with higher precision than previous experiments. In order to do this muons are created from protons hitting the target and are then sent to the M4 and M5 lines to be injected into the storage ring. The storage ring only accepts muons with momentum within 0.2% of 3094 MeV/c. In order to decrease the number of lost muons a wedge was placed in the M5 beam line to utilize the properties of ionization cooling to create a more uniform momentum spread. Previous simulations predicted a much larger gain of storable muons than the experimental results showed. In order to determine the cause of this discrepancy, simulations were run using a GEANT4 based code to track muons through the M4 and M5 lines, the inflector, and the storage ring while adjusting the orientation, material, geometrical parameters and studying the performance of this wedge for a wide range of incoming muon energies.
