(DURIP) LABORATORY DIFFRACTION CONTRAST TOMOGRAPHY FOR 3D MICROSTRUCTURE CHARACTERIZATION
Abstract
This proposal requests funds for the acquisition of a laboratory diffraction contrast tomography instrument (labDCT), to be added to an existing Zeiss ConteXT micro computed tomography (microCT) unit. This instrument will be used by the coPIs’ research groups and several other groups within the College of Engineering and the Mellon College of Science at Carnegie Mellon University to perform nondestructive 3D studies of important engineering materials. Nondestructive 3D characterization techniques usually require the use of high brilliance focused synchrotron xray beams? the requested instrument brings this capability to the researcher’s lab by using a polychromatic xray beam instead of the monochromatic synchrotron beam. In a typical experiment, the sample is rotated in the xray beam and absorption images are recorded on a flat panel detector.
