论文摘要
虽然长期以来已经认识到高能X射线和伽玛射线极化的科学潜力，但测量高能光子的极化是挑战性的。迄今为止，从天体物理来源检测很少。但是，最近的技术发展增加了可能在不远的未来发生变化的可能性。在伽马射线爆发（GRB）极化器和极化敏感的康普顿望远镜的发展中取得了重大进展。 A second-generation dedicated GRB polarimeter, POLAR-2, is under development for launch in 2024, and COSI a second-generation polarization sensitive Compton Telescope has been selected by NASA for launch in 2025. This chapter reviews basic concepts and experimental approaches of scattering polarimetry of hard X-rays to MeV γ-rays, and pair production polarimetry of higher-energy photons
While the scientific potential of high-energy X-ray and gamma-ray polarimetry has long been recognized, measuring the polarization of high-energy photons is challenging. To date, there has been very few significant detections from an astrophysical source. However, recent technological developments raise the possibility that this may change in the not-too-distant future. Significant progress has been made in the development of Gamma-ray Burst (GRB) polarimeters and polarization sensitive Compton telescopes. A second-generation dedicated GRB polarimeter, POLAR-2, is under development for launch in 2024, and COSI a second-generation polarization sensitive Compton Telescope has been selected by NASA for launch in 2025. This chapter reviews basic concepts and experimental approaches of scattering polarimetry of hard X-rays to MeV γ-rays, and pair production polarimetry of higher-energy photons
