The results of the LLNL/UCLA inverse free electron laser (IFEL) experiment are presented. A 500 mJ 120 fs Ti:Saph laser pulse interacts with a short electron beam in a planar undulator tapered both in magnetic field strength and period to accelerate the electron beam. The tapering of the undulator maintains resonant energy exchange between the laser and electron beam while the electron beam's energy increases. We observe an energy modulation from 77 MeV to 120 MeV. Through use of simulations that are consistent with the observed data, we report a peak acceleration gradient of at least 180 MeV/m.
