The production rates of prompt and non-prompt J/ψ and ψ(2S) mesons are measured using 2.1 fb⁻¹ and 11.4 fb⁻¹ of data collected with the ATLAS experiment at the LHC, in proton-proton collisions at √s=7 and 8 TeV respectively. Production cross-sections for both prompt and non-prompt production sources, ratios of ψ(2S) to J/ψ production, and fractions of non-prompt to inclusive production for J/ψ and ψ(2S) are measured double-differentially as a function of meson pT and rapidity. These measurements are made in a restricted fiducial volume and also corrected for geometrical acceptance after which they are compared to a variety of theoretical predictions.
