Multiple X-ray coincidence method and its application to element quantification

Oshima, Masumi; Murakami, Yukihiro*; Koizumi, Mitsuo ; Toh, Yosuke   

So far we have demonstrated that the $$gamma$$-ray coincidence method (the multiple $$gamma$$-ray detection method) is a versatile method to achieve high resolution and high signal-to-noize ratio in nuclide determination. To extend this method we propose the X-ray coincidence method (the multiple X-ray detection method). We present a result of this method by using two low energy photon spectrometers and a standard $$gamma$$-ray source of $$^{152}Eu$$ for activation of atoms. We could observe a peak in two dimensional X-ray matrix, which originates from coincidence of K-X and L-X rays. We demonstrated that background is reduced on the matrix.
