      Beamline Description
      The X-ray Powder Diffraction (XPD) beamline at NSLS-II consists of two branch lines, the high- resolution powder diffraction beamline, XPD-2 and the dedicated Atomic Pair Distribution Function (PDF) beamline, XPD-1. The damping wiggler, DW100 delivers a large energy band-pass white X-ray beam into the First Optical Enclosure (FOE) of the beamline. The horizontally focusing Side Bounce Monochromator (SBM) at XPD-1 receives the part of the white beam that is transmitted through the first crystal of the XPD-2 Double Laue Monochromator (DLM). The SBM is used to select the X-ray photon energy at XPD-1. The vertical focusing of the beam is achieved by using a long bent mirror mounted further downstream in the FOE. XPD-1 offers rapid data acquisition rates (30 frames/s) and high flux required for in-situ operando studies. A wide variety of sample environments including (80 – 500) K Liquid nitrogen cryostream, (5-500) K cryostat, (0-5) T superconducting magnet and gas flow-cells are available at the beamline. Beamline is equipped with an automatic capillary sample alignment system. XPD-1 offers real-time data processing and analysis capabilities with a suite of user-friendly robust software.
