Abstract: We report the test of many of the key elements of the laser-based calibration system for muon g – 2 experiment E989 at Fermilab. The test was performed at the Laboratori Nazionali di Frascati’s Beam Test Facility using a 450 MeV electron beam impinging on a small subset of the final g – 2 lead-fluoride crystal calorimeter system. The calibration system was configured as planned for the E989 experiment and uses the same type of laser and most of the final optical elements. We show results regarding the calorimeter’s response calibration, the maximum equivalent electron energy which can be provided by the laser and the stability of the calibration system component
