Development of a high-energy transmission LAUE diffraction setup using a medical linac

In the present experimental setup, High-energy X-ray (HEX-ray) generated from a Linear Accelerator (LINAC) was used for the development of High-Energy Transmission Laue Diffraction (HETLD) setup. The HETLD is an useful experimental technique for the structural characterization of challenging materials such as liquids, amorphous, nanomaterials etc. High-energy X-rays are very hard X-rays, with typical energies of 60-1000 keV about one order of magnitude higher than conventional X-rays. The HEX-rays bear unique advantage over conventional hard X-rays for the analysis of advanced materials. HEXray generated using a medical LINAC set at 6MV was used in the present setup of HETLD. Again, the HETLD is a tool for mapping grain-level orientation and strain in thicker metallic polycrystals. Preliminary trial run of high-energy X-ray diffraction were presented. (author)
