Abstract

We report simulation results of pair production by ultra-intense lasers\nirradiating a gold target using the GEANT4 Monte-Carlo code. Certain\nexperimental features of the positron and electron energy spectra are\nreproduced, as well as trends with regard to target thickness and hot electron\ntemperature Te. For Te in the range 5-10 MeV, the optimal target thickness for\npair production is found to be about 3 mm. Further Monte-Carlo simulations may\naid in the optimization of laser-driven positron sources.\n
