Back-scattering Laue with data acquisition using a fast 2D detector; sample stage with multi-axis rotations and full translation capabilities controlled by multi-function joystick allowing for real time sample movement/rotation with simultaneous data visualization; optical camera setup to allow for precision alignment of sub-mm crystals or exploration of the position dependence of diffraction patterns. Laue pattern processing and indexing using NorthStar Real-Time Orientation software. Radiation: non-monochromatic W source.Main optics: Four choices of primary collimators for x-ray beam diameters 0.5, 1, 2 and 3 mm; three-axis rotation goniometer with X,Y,Z translation orientation base; Multiwire MWL120 2D detector with CO2+Ar gas consisting of arrays of 20-microns W wires coated with Au. An optional 2mm brass collimator/elliptical mirror also exists, which allows for simultaneous viewing of both the beam position on sample in real space and the associated diffraction pattern.
