摘要:

本文总结了一个成功的项目,LAUE的发展,由意大利航天局(ASI)的支持,并致力于发展长焦距(高达100米)劳厄透镜的硬X-/软伽马射线天文学(80-600千电子伏)。该设备已准备就绪,原型透镜瓣的组装正在进行中。这个项目的伟大成就是使用弯曲晶体。从单晶上获得的测量和模拟,我们已经估计了预期的点扩散函数,从而花瓣制成的透镜的灵敏度。预期灵敏度为几个$\times10^{-8}$光子cm $^{-2}$ s $^{-1}$ keV $^{-1}$。我们讨论了一些开放的天体物理学问题,可以解决这样一个仪器搭载在一个自由飞行的卫星。

英文摘要:

This paper summarizes the development of a successful project, LAUE, supported by the Italian Space Agency (ASI) and devoted to the development of long focal length (up to 100 m) Laue lenses for hard X--/soft gamma--ray astronomy (80-600 keV). The apparatus is ready and the assembling of a prototype lens petal is ongoing. The great achievement of this project is the use of bent crystals. From measurements obtained on single crystals and from simulations, we have estimated the expected Point Spread Function and thus the sensitivity of a lens made of petals. The expected sensitivity is a few $\times10^{-8}$ photons cm$^{-2}$ s$^{-1}$ keV$^{-1}$. We discuss a number of open astrophysical questions that can settled with such an instrument aboard a free-flying satellite.
