General Area Detector Diffraction

Area Detectors. A two-dimensional or area detector attached to a powder diffractometer can gready decrease data collection time. Many diffraction appHcations require so much time with a conventional detector that they are only feasible if an area detector is attached to the iastmment. The Siemens General Area Detector Diffraction System (GADDS) uses a multiwire area detector (Fig. 17). This detector measures an x- and ajy-position for each x-ray photon detected. The appHcations foUow.

Generally, an area detector permits one to check the sample quality much faster and more conclusively, because of easier visualization. Thus if a supposed single crystal gives a set of powder diffraction rings or an amorphous-state halo, the operator will see this immediately it would take a lot of time and expertise to extract this from the results of a random search ...
