摘要:

正在开发一些技术,以解决康普顿望远镜和望远镜对之间存在的巨大灵敏度差距,并将偏振测量扩展到MeV伽马射线世界。我的特点的一个活跃的目标的属性,详细说明了各种贡献的角分辨率,使用一个完整的五维事件发生器的贝特-海特勒微分截面。用同样的工具,我还检查了在转换晶片中的多重散射引起的偏振不对称性的稀释。

英文摘要:

A number of techniques are being developed to solve the monstrous sensitivity gap that exists between the energy ranges of good sensitivity of the Compton and of the pair telescopes and to extend polarimetry to the MeV gamma-ray world. I characterize the properties of an active target, detailing the various contributions to the angular resolution, using a full five-dimensional event generator of the Bethe-Heitler differential cross section. With the same tool I also examine the dilution of the polarization asymmetry induced by multiple scattering in the conversion wafer.
