In order to improve the ⁹⁹Mo production yield of a W-MoO₃ target system, photon generation at a W converter and photon generation at a MoO₃ target were investigated as functions of the W thickness. The two separate sets of results were then analyzed to find the W thicknesses that lead to improved ⁹⁹Mo yields.
