High Resolution Computed Tomography in Laboratory Environment — Randolf Hanke1,2, •Simon Zabler2, and Fella Christian1 — 1Chair of X-Ray Microscopy, University Würzburg — 2Fraunhofer Entwicklungszentrum Röntgentechnik, Flugplatzstrasse 75, 90768 Fürth
From organic or metallic micro-structures to whole engines, 3D non-contact measurements by Computed Tomography(CT)have become an indispensable tool for a broad range of users. The Chair of X-Ray Microscopy and the Fraunhofer Development Center for X-Ray Technology develop CT as a versatile tool for materials development and inspection, covering a multi scale range in resolution and sample size. Depending on the application, e.g. carbon fiber composites are imaged at sub-micrometer resolution, whereas complete cars are scanned by MeV X-rays in a XXL CT-lab. Among many characterization techniques, X-Ray nano CT stands out with its unique capability to measure non-invasively the three-dimensional architecture of natural and man-made nano materials. This presentation will give an overview about current results, which benefit the comprehension of macromolecular biology and new nano-structured technical materials. Reasonable results can only be achieved by controlling the complete analytical process, from sample preparation, X-Ray imaging at the nano scale,volume reconstruction to final data analysis. High resolution CT imaging is presented at the micro/nano scale by a modified Scanning Electron Microscope (SEM), a Liquid Metal Jet(LMJ)X-Ray system and a new X-Ray Nano Tube for some selected applications.
