The slits that are in use are selected for somewhat better resolution than one would find on other instruments. The instrument is currently outfitted with a set of beam and detector slits that balance the needs of resolution and intensity for typical runs. The instrument is suited for identification of unknown phases, quantitative analysis and refinement of crystal structures. Xrd photo Rigaku Ultima IV w/ Bragg-Brentano geometry DS SS RS - mode DS SS 37 BB vs. Moreover in the Debye-Scherrer geometry the powder samples are measured in tiny glass capillaries, useful for air-sensitive samples. In both configurations the sample can spin in order to minimize crystallites preferred orientations. 1, even though it is common in synchrotron powder XRD experiments. Thanks to the Pre-aligned Fast Interchangeable X-ray modules (PreFIX), X'Pert PRO MPD system can be easily swiched in few minutes, without the need for re-alignment of the modules, between a Bragg-Brentano parafocusing setup and a Debye-Scherrer geometry. correction for BraggBrentano (reection) geometry (McCusker etal., 1999) given by ¼ 2dcosðÞ R.Todate,no correction equation has been published for a at area detector in the DebyeScherrer geometry shown in Fig. The X'celerator detector, that implements the latest RTMS (Real Time Multiple Strip) X-ray detection technology, allows data collection at rates about 100 times faster than conventional single-point counters.The instrument is outfitted with a set of slits for incident and diffracted beams that balance the needs of resolution, intensity of the peaks and minimization of the background. It is necessary to take into account the effects of the instrument. The source is the high power ceramic tube PW3373/10 LFF with Cu anode. Powder X-ray diffraction peak profile varies on instruments and conditions of measurements. The laboratory for the X-Ray Powder Diffraction analisys is equipped with a diffractometer system PW3040/60 X'Pert PRO MPD from PANalytical. Measurements of X-ray diffraction patterns of high-T c superconductor and tungstencarbide powder samples using a BraggBrentano diffractometer showed systematic variations of the intensities for different preparation conditions.
