This paper presents multi dimensional approaches for material identification applied on experimental X-ray measurements obtained with CdTe spectrometric detector. LETI has been developing a 16 channels fast read-out electronics capable to perform spectrometric measurements at count rates above 107 counts/s. The read-out electronics was coupled to CdTe linear array pixel detectors. A multidimensional analysis of the measured spectra has been developed to perform material identification. The results show a decrease of false detection rate by a factor up to 2 compared to an optimised dual counting approach applied on the same spectrometric raw data. Compared to a sandwich detector, the false detection rate is decreasing by a factor higher than 3 for thin objects. Generally, the paper demonstrates quantitatively the continuous performance and robustness increase with the number of detector energy channels. |
