Experimental study of a BaFBr:Eu image plate detector depending on dose, spectrum of pulse X-ray source, and scan number

The possibility of application of phosphor with memory effect for X-ray recording of fast (explosive) processes has been studied. Four different radiation sources were used in the series of experiments carried out. To obtain numerical X-ray images, a detector based on BaFBr:Eu Image Plate phosphor was used. It has been found that the summation of results of several scans after single exposition allows improving the signal-to-noise ratio and dynamic range of the readable signal. Spectra of pulse X-ray devices have been calculated on the base of calibration curves of radiation attenuation for different materials. Preliminary experiments on the registration of explosive processes have been conducted.
