摘要
为了满足国内外空间X射线探测的需求, 研制了可透过X射线同时阻挡紫外可见红外波段杂散光的X射线遮光膜。利用紫外可见分光光度计和同步辐射光源对遮光膜的光学性能进行了表征, 并对其几何结构和光学性能的关系进行了分析。实验结果表明: 在紫外、可见和红外波段, 聚酰亚胺表面铝膜的厚度越大, 其透过率越低, 聚酰亚胺表面蒸镀厚度为120 nm铝膜时遮光膜的透过率已低于1.0×10-4; 且聚酰亚胺表面单面镀铝的遮光膜的挡光效果优于双面镀铝的遮光膜。在X射线波段, 遮光膜的透过率只取决于聚酰亚胺的总厚度和铝膜的总厚度, 与分层结构无关。本课题组自行研制的遮光膜基本满足目前国内空间探测项目的需求。
Abstract
In order to satisfy the requirements of space X-ray surveys at home and abroad, some X-ray filters could be used in space project were manufactured. First, the transmission properties were characterized by UV-V is spectrometer and X-ray source of synchrotron radiation. The relationship between the optical properties and geographic structure of X-ray filters was studied. The results indicate that in the ultraviolet, visible, and infrared bands, the transmission decreased as the thickness of the Al layer increased. The transmission of filters, whose Al layers are deposited on one side of polyimide, is lower than that whose Al layers are deposited on both sides of polyimide. The transmission is less than 10-4 while the thickness of Al layers is 120 nm. In the X-ray band, the transmission is determined by the whole thickness of polyimide and the whole thickness of Al. The proposed filters can satisfy the present requirements of space X-ray surveys.
