     2588
     2589<p class=MsoNormal>1) Bragg-Brentano laboratory powder diffractometer</p>
     2590
     2591<p class=MsoNormal>The conventional arrangement of this experiment is to have a
     2592flat sample with incident and diffracted beams at equal angles (theta) on
     2593opposite sides of the sample. The sample is frequently spun about its normal to
     2594improve powder statistics and impose cylindrical symmetry on any preferred
     2595orientation (texture). Thus, the diffraction plane (source, diffraction vector
     2596&amp; detector) contains the K-vector which is parallel to the diffraction
     2597vector and <a name="_Hlk74813217"><span style='font-family:Symbol'>W</span>, </a><span

     2602<p class=MsoNormal><span style='font-family:Symbol'>2) </span>Debye-Scherrer
     2603diffractometer with point detector(s)</p>
     2604
     2605<p class=MsoNormal>The usual arrangement here is to have a capillary sample
     2606perpendicular to the diffraction plane. The capillary may be spun about its
     2607cylinder axis for powder averaging and to impose cylindrical symmetry on the
     2608texture which is perpendicular to the diffraction plane. Thus, <span

     2610and <span style='font-family:Symbol'>C =90.</span></p>
     2611
     2612<p class=MsoNormal>3) Debye-Scherrer diffractometer with 2D area detector</p>
     2613
     2614<p class=MsoNormal>The area detector is presumed to be directly behind the
     2615sample with the incident beam somewhere near the center of the detector. The
     2616detector axes are defined (for a synchrotron) with the X-axis toward the
     2617synchrotron ring and the Y-axis vertical “up”; one views the detector image as
     2618if looking from the x-ray source. The sample is assumed to be a capillary
     2619(which may be spun to impose cylindrical symmetry), although other sample
     2620shapes may be used, and is aligned with the cylinder axis horizontal. Integration
     2621of the image from a series of “caked” slices gives a set of powder patterns,
     2622each assigned an azimuthal angle where zero is along the X-axis. Thus, this
     2623diffraction plane is horizontal and contains the cylinder axis so <span
