论文摘要
可调的伽马射线镜头已成为过去讨论的古典固定能laue镜头的有前途的选择。我们在这里描述了我们在微型基座上进行单轴倾斜调整的开发工作。我们还概述了光学系统的设计，能够监视所需的许多晶体的对齐。可调节晶体基座的另一个好处是，它既可以减轻晶体安装中高精度的需求，又可以减轻对晶体安装的支撑平台长期稳定性的严格要求。此外，将各个晶体安装在单独的基座上有助于使用双层晶体。 关键字：伽马射线天文学，望远镜技术，劳埃镜头
The tunable gamma-ray lens has turned out to be a promising alternative to the classical fixed-energy Laue-lenses discussed in the past. We describe here our development work on a miniature pedestal with one-axis tilt adjustment. We also outline our design for an optical system, capable of monitoring the alignment of the many crystals needed. An added benefit of the tunable crystal pedestal is that it relieves both the demands for high precision in the crystal mounting and the stringent requirements for long-term stability of the support platform on which the crystals are mounted. Moreover, mounting the individual crystals on separate pedestals facilitates the use of double layers of crystals. Keywords: Gamma-ray astronomy, Telescope technology, Laue lenses
