Measurement of the spatial polarization distribution of circularly polarized gamma rays produced by inverse Compton scattering

Inverse Compton scattering of polarized laser photons by energetic electrons is an excellent method to generate gamma rays. A 100% can rays, but polarization varies depending on the angle In this study, we experimentally measure spatial distribution circularly rays using a magnetized iron that circular MeV Measurements asymmetry gamma-ray transmission relative at each clearly show are near central axis, and they change from linear as increases. simple way obtain highly use collimator transmits only axis with such characteristics. Polarized are, indeed, generated ${90}^{\ensuremath{\circ}}$ collisional inverse between electron beam laser.
