In the measurement, we utilized a mosaic silicon crystal and a comb silicon crystal for diffracting a gamma-ray and obtaining the energy-angle correlation, because these crystals have angular acceptances large enough to obtain a practical gamma flux even after the diffraction [3]. An experiment was carried out at the laser Compton gamma-ray beamline at NewSUBARU. We generated a gamma-ray at 1.7 MeV by injecting a CO2 laser to the storage ring operated at 1 GeV and the crystal was put on the gamma-ray beam path to diffract the gamma-ray. We measured energy spectra of the diffracted gamma-ray by a high-purity Germanium detector with rotating the crystal. The measured spectra were used for reconstructing the energy-angle correlation of the gamma beam. We report the experimental procedure and the measurement results., Nuclear Photonics (NP2020)}, title = {Energy-Angle Correlation Measurements of Laser Compton Scattered g-rays}, year = {2021} }
