内容記述 |
Highly polarized MeV gamma rays produced via inverse Compton scattering (ICS) between a polarized laser and electron beam provide a unique probe for fundamental and applied physics. ICS gamma rays are characterized by energy tunability, quasi-monochromaticity, high polarization, and low divergence angle (<1 mrad), and are used for accelerator beam diagnostics, nuclear physics experiments, and evaluation of detectors for polarized gamma rays. A polarimeter that can measure the spatial polarization distribution of gamma rays is being developed at the UVSOR synchrotron facility. The measurement principle exploits the azimuthal asymmetry in Compton scattering cross-sections. Incident linearly polarized gamma rays interact with an iron target. Seven NaI detectors arranged in the scattering plane record the angular intensity distribution of scattered gamma rays. The determination of the polarization axis is achieved through systematic analysis of the azimuthal modulations. The spatial polarization distribution is measured by scanning a 1-mm diameter collimator in the beam cross-section in two dimensions. Here, we discuss the results of the gamma-ray polarization axis measurement relative to the laser polarization axis measured when the collimator position is along the central axis of the gamma-ray beam. |
