智能x射线光学项目是由英国的五个机构组成的联盟,研究用于大型和小型应用的主动/自适应x射线光学。大规模应用的目标是未来用于x射线天文学的x射线望远镜。这里介绍的工作包括建模和测试新的大型原型薄壳光学器件,该器件集成了压电装置,使表面能够主动变形,以达到比目前可用的(例如钱德拉0.5英寸)更好的角分辨率。由于外壳很薄,可以实现高度嵌套,从而可以结合高角度分辨率提供非常大的收集区域。在莱斯特大学的x射线束流线上对这个原型进行测试的结果将被展示。讨论了压电器件的驱动对检测图像的影响,以及系统控制软件的开发。改进的全宽度的一半最大的焦点高达25%,但到目前为止,这还没有在一个可控的方式完成。给定一组电压下获得的表面图形是稳定的,但是检测到压电器件之间明显的相互作用或耦合,并且仍然无法解释。
The Smart X-ray Optics project is a UK based consortium of five institutions investigating active/adaptive X-ray optics for both large and small scale applications. The large scale application is aimed towards future X-ray telescopes for X-ray astronomy. The work presented here includes the modelling and the testing of the new large scale prototype thin shell optic which incorporates piezoelectric devices to enable the surface to be actively deformed aiming to achieve an angular resolution better than that currently available (e.g. Chandra 0.5"). As the shell is thin, a high degree of nesting is possible such that very large collecting areas can be provided in combination with the high angular resolution. The results from the testing campaign for this prototype in the X-ray beam line at the University of Leicester will be presented. The effect of the actuated piezoelectric devices on the detected image and software development for control of the system are discussed. Improvement of the Full width Half Maximum of the focus spot of up to 25% was seen but as yet this has not been completed in a controlled way. The surface figure achieved with a given set of voltages is stable, but an apparent interaction or coupling between the piezoelectric devices was detected and is still unexplained.
