DESCRIPTION:Speakers: Anton Narikovich (Imanuel Kant Baltic Federal Univer
 sity)\nA promising direction of development of modern X-ray optics is an o
 ptical system\, based on the compound refractive lenses (CRLs). Main appli
 cations of CRLs are microfocusing and X-ray microscopy. In order to improv
 e a technology of X-ray optics manufacturing it is urgent to develop an ef
 fective approach of precise nondestructive CRL metrology.\nAt this work\, 
 we report the assessment of the efficiency of non-destructive inspection 
 – a high-resolution x-ray computed tomography (HRXCT). This technique al
 lows to realize non-destructive testing irregularities\, the presence of v
 oids\, inclusions in lenses material and at the same time to analyze the s
 hape and geometric parameters: the coaxiality\, the distance between the r
 efracting surfaces and shape of refractive surfaces.\nHRXCT was performed 
 using the X-ray inspection system YXLON designed for generating high-quali
 ty X-ray images with the 1 µm resolution. We present the CT imaging resul
 ts of lenses made of high-purity aluminum with the parabola apex radii of 
 50 µm.\nComparing the obtained images with specified requirements of the 
 geometrical characteristics of the lenses\, the quality of the refractive 
 surface and internal size of defects allows us to estimate the lens manufa
 cturing quality.\n\nhttps://indico.inp.nsk.su/event/3/contributions/1181/
