摘要
设计并成功研制了单毛细管椭球镜,并通过光学及X射线方法测试了它的特性。椭球镜的面形误差为15 μrad,能量为9 keV时聚焦光斑直径为40 μm,聚焦光斑发射角为1.75 mrad。基于研制的椭球镜,在上海光源X射线成像线站搭建X射线纳米成像系统,并实现了纳米成像,这表明该椭球镜可满足X射线纳米成像的需求。
Abstract
An ellipsoidal mono-capillary is designed and fabricated, and its performance is measured by both optical measurement and X-ray testing. The profile errors of the ellipsoidal mono-capillary is 15 μrad. The diameter of focusing spot is 40 μm and the launching angle of focusing spot is 1.75 mrad at energy of 9 keV. Based the developed ellipsoidal mono-capillary, a X-ray nano-imaging system is designed and constructed at the X-ray imaging beamline (BL13W1) in Shanghai synchrotron radiation facility (SSRF). The X-ray nano-imaging is achieved with utilization of the ellipsoidal mono-capillary, which indicates that the ellipsoidal mono-capillary can meet the requirement of X-ray nano-imaging.
