• Energy-variable gamma-rays are produced in the laser Compton slant-scattering in the Shanghai laser electron gamma source (SLEGS) beamline of the Shanghai Light Source. An interaction chamber composed of the rotating laser optical system, shielding finger, and reference-target insertion device was developed to ensure slant scattering in the angular range of 20–160°, producing gamma-rays in the energy range of 0.66–21.1 MeV with a flux of 4.8 × 105–1.5 × 107 photons/s. SLEGS is the first slant-scattering beamline which systematically produces energy-variable gamma-ray beams and continuously tune the gamma-ray energy in the laser Compton slant-scattering. We report on designed performance of the slant-scattering and results of a test run.
