论文摘要
提出了MEV能量带中天文望远镜的新概念。这个概念是基于过去讨论过的晶体中的布拉格衍射，但是到目前为止，对广泛的能量范围的敏感性似乎已经遥不可及。在本文中，我们指出，如果我们找到在轨道上调整镜头所有晶体的个体倾斜的方法，则可以在几个观察步骤中以极好的效率覆盖一个镜头，从200 keV到2.5 mev。其次，我们注意到，使用双晶层的镜头将大大增加光子的收集。在随附的论文中，我们更详细地描述了我们的整体镜头设计，并介绍了我们的第一个原型倾斜调整基座，以与单个镜头相使用。 KeyOrds：伽马射线天文学，望远镜技术，laue镜头
A new concept for an astronomical telescope in the MeV energy band is presented. The concept builds on Bragg diffraction in crystals, which has been discussed in the past, but so far a design with good sensitivity over a wide energy range has seemed out of reach. In this paper we point out that if we find ways to adjust, in orbit, the individual tilt of all the crystals in the lens this would allow one single lens to cover with excellent efficiency the full range of energies from 200 keV to 2.5 MeV in a few observation steps. Secondly, we note that the use of lenses with double crystal layers will increase the photon collection significantly. In an accompanying paper we describe our overall lens design in more detail and present our first prototype tilt adjustment pedestal for use with the individual lens facets.
