With a high-intensity, rotating Cu anode (line source = 0.1×10 mm), the  TTRAX III (18kW) theta-theta vertical diffractometer is equipped with Cross Beam Optics (CBO) which enables simple configurational change from Bragg-Brentano (parafocusing) to parallel beam optics. A bent/flat graphite monochromator and a scintillation detector are aligned in the diffracted beam. There is also a video camera for positioning the sample. The basic sample holder is an Euler cradle, which, in addition to providing precise sample alignment, ensuring exact peak position in powder diffraction patterns, allows the analysis of texture and residual stress, as well as thin film reflectivity.  The TTRAX III is the only diffractometer of its kind in Israel and Europe; there are a few in the United States.
