Many research and applications areas require photon sources capable of producing Gamma-ray beams in the multi-MeV energy range with reasonably high fluxes and compact footprints. Besides industrial, nuclear physics and defense applications, a considerable interest comes from the possibility to assess the state of conservation of cultural assets like statues, columns etc. via visualization and analysis techniques using high energy photon beams. Computed Tomography scans presently provide high quality three-dimensional imaging in industry, museums and medical diagnostics. We propose an innovative scheme based on Inverse Compton Scattering of a high intensity ultra-violet (UV) beam generated in a free-electron laser (FEL) by the primary electron beam. The novel scheme can produce quasi-monochromatic UV radiation in the 15-20 eV range, and gamma-rays in the 10-20 MeV range.
