A new Curved Image Plate Detector (CIPD) has been designed for X-ray diffraction investigations of ceramics using synchrotron radiation. It has been configured primarily for use with the Quadrupole Lamp Furnace (QLF), a thermal image furnace, which can be used to heat samples up to 2000 °C in air. The CIPD is a curved, one-dimensional detector which simultaneously records the entire diffraction pattern in the 28 range from 0° to 37°. An on-site reader enables extraction, transfer, and storage of X-ray intensity information in ≤ 30 seconds. The CIPD shows narrow reflection half-widths and together with QLF has enabled rapid acquisition of high resolution X-ray diffraction patterns suitable for structural refinement. Selected results from high temperature X-ray diffraction studies using the CIPD+QLF setup are presented to demonstrate the potential of this setup for a variety of applications such as determination of true thermal expansion, or phase transformation behavior of materials, etc.
