BL15 : experimental equipment

Debye-Scherrer camera

A transmission-geometry powder diffractometer, Debye-Scherrer camera is now available in the BL15 experimental hutch (Table 1 & Figs. 1, 2). As a detector, the camera has an imaging plate (IP) on the 2θarm. A powder sample is sealed in a glass capillary with a diameter of 0.1-0.5 mm and rotated at a speed of ~60 rpm during measurements. The station is equipped with an off-line IP reader (Fig. 3). The two-dimensional diffraction image (Fig. 4) can be transformed into one-dimensional powder diffraction data using image-analysis software. NIST standard reference materials (SRMs), silicon powder (640c) and lanthanum hexaboride powder (660a), are also available for use as line position standards.
