Abstract:
A multi-contrast x-ray imaging facility with a single x-ray absorption grating is developed at the X-ray Imaging beamline (BL-04), Indus-2 synchrotron radiation source, India, and implemented in both monochromatic and white beam operation modes of the beamline for versatile utilization of this technique in structural characterization of a wide range of samples from soft biological to metallic, dense, and thick materials. The developed facility is characterized by resolution, visibility, and signal-to-noise ratio and tested for static and dynamic morphological analysis under different experimental conditions. The qualitative and quantitative analysis of extracted multi-contrast x-ray images of different samples demonstrates the relative merits of various experimental conditions. This unique multi-contrast facility with a single x-ray absorption grating that operates in dual modes of the X-ray Imaging beamline enables the study of both static and transient phenomena across a wide range of applications at the beamline.
