摘要：

The design, construction and performance of a new X-ray camera allowing simultaneous sampling of diffraction data both in the small- and in the wide-angle range are described. The instrument employs line collimation and contains two position-sensitive gas detectors covering distance ranges of 10-1000, and 3.4-4.9 angstrom, respectively, which are regions of strong interest in studies on polymer and liquid crystal structure. The detection system is time-multiplexed with free selection of the fractional live times in the two regions to adapt to signal intensity differences. The camera is specifically designed to study structural transitions and annealing phenomena where simultaneous measurement in both regions under identical conditions is essential.
