Spectrum Matching Applied in Design of the X-ray Machine
光谱匹配在X光机设计中的应用

By combining the X-ray imaging technology and the low light level imaging technology,the research group designed the novel combined X-ray image intensifier. Before the design,the spectrum compatibility between Gd2O2 S : Tb,CaWO4 intensifying screens and Super S252 Super S251 photo cathode was analyzed,and the calculated values were 0.644,0.761,0.369,0.571 respectively. Basing on the spectral matching curves and the spectral matching factor values,the combination of Gd2O2S : Tb screen and Super S252 photo cathode was chosen for the X-ray intensifying system of the novel X-ray machine,which was of high imaging performance.
