Abstract
An electron beam is obtained using laser wakefield electron accelerator, and
converted into a γ-ray source after undergoing bremsstrahlung radiation in a
dense material. A quasi-monoenergetic structure is observed when the length of the
plasma channel was modified. The structure has a 58-MeV peak energy, 15-mrad
(full-width at half-maximum) divergence angle, and 340-pC charge. The γ-ray
source generated by this high-quality electron beam is brighter and has higher
spatial and temporal resolutions than other conventional sources. A γ-ray
radiography demonstrational experiment is performed. Pictures of a ball with
different layers made of different materials are taken. The results show a clear
structure and density resolution.
