Television-type X-ray detectors are position sensitive detectors which permit rapid recording and readout of two-dimensional diffraction patterns wigh high spatial resolution. In Photon Factory, this kind of detector will be extensively used in <I>in situ</I> observation of X-ray topographs from single crystals under dynamic structural change. Strong intensity of synchrotron radiation will allow one to improve the spatial and time resolution of the detector and apply the method to studies on various transient phenomena. Another promising application of the detectors is to rapid acquisition of structure factor data from macro-molecular crystals. Incorporation of the detector to a fast digital memory device makes it possible to store the number of X-ray photons detected by each picture element at a television scanning rate. More than two order of magnitude higher data collection rate is expected over the standard diffractometer.
