Accuracy of intensity measurement by use of an area detector with a photostimulable phosphor screen, as confirmed by measuring scattering intensity from a liquid

An area detector using a photostimulable phosphor screen, namely an imaging plate (IP), has been applied to the intensity measurement of X-ray scattering from liquid CCl4. The scattering intensity in the present experiment has been compared with that determined by means of an energy-dispersive method. The two intensities have agreed well with each other. It has been proved that the use of the IP detector makes it possible to measure the scattering intensities of halo patterns precisely with much shorter accumulating time with a simple procedure of analysis and that there is no effect of the oblique incidence of scattering X-rays to the IP at high scattering angles.
