摘要：

Recoiled Compton electrons of 180 deg have been utilized to measure the energy distribution of high-intensity bremsstrahlung. An optimized detector-collimator configuration was used for detection and spectrum measurement of recoiled electrons. The spectrum has been reconstructed using Compton cross sections retrieved from the ENDF/B.VIII.0 library. The measured spectrum has been further validated using theoretical simulation by the Geant4 code with incorporating ENDF/B-VIII.0-recommended cross sections. The simulated spectrum matches the measured spectrum if the spatial spread and energy spread of the electron beam are accounted for in the simulations.
