可调gamma-ray透镜技术
Technologies for tunable gamma-ray lenses
摘要：
可调谐伽玛射线透镜已被证明是一个有前途的替代经典的固定能量劳厄透镜在过去的讨论。我们在这里描述我们的开发工作的微型基座与单轴倾斜调整。我们还概述了我们的光学系统的设计，能够监测所需的许多晶体的对齐。可调晶体基座的另一个好处是它缓解了对晶体安装的高精度要求和对晶体安装在其上的支撑平台的长期稳定性的严格要求。此外，将单个晶体安装在单独的基座上有利于使用双层晶体。关键词：伽玛射线天文学，望远镜技术，劳厄透镜
英文摘要：
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
