BM32 upgrade Laue microdiffraction setup


  • Share

An upgraded Laue microdiffraction setup has been implemented on BM32 (CRG-IF). Laue micro-diffraction uses a broadband white microbeam (5–22 keV) combined with sample-scanning and a 2D detector for mapping strain and orientation in polycrystals. The new setup uses fixed-curvature ion-beam-polished KB mirrors mounted on hexapods for micro-focusing, which provide larger acceptance and reduced beam size at the sample. Precise translation stages for the microscope and a piezoelectric shutter were also added. The LaueTools data analysis software suite enables the automatic treatment of Laue maps and the display of 2D orientation and deviatoric strain fields.
