X-RAY / ENERGY DIFFERENTIATION TYPE 64 CH GAMMA-RAY CdTe RADIATION LINE SENSOR DETECTOR C10413 Accomplish X-ray and gamma-ray images with multicolor by energy differentiation FEATURES ●High radiation detection efficiency due to direct conversion type semiconductor (CdTe) detector ●Simultaneous energy differentiation of input radiation photons by setting 5 different energy thresholds ●Parallel signal readout from each pixel ●High counting efficiency ●Eliminating effect from beam scattering and hardening by energy differentiation function ●Wide energy measurement range covering X-rays and gamma-rays spectral regions Application 1: Simultaneous measurement of images at different energy regions – Energy-differentiated RI* images – Images were measured by linear scanning over radioisotopes (RI) with the radiation line sensor. Energy-differentiated imaging allows color visualization and identification of different radioisotopes. Images from different radioisotopes can be visualized by energy discrimination for easy color identification. * RI: radioisotope Energy-differentiated images Radioisotope arrangement Composite image with energy-differentiation ENERGY (keV) Image obtained with 137Cs only (Energy: 140 keV or higher) 140 70 35 ENERGY THRESHOLD LEVEL 1 ENERGY THRESHOLD LEVEL 2 ENERGY THRESHOLD LEVEL 3 TIME Image obtained with 57Co only (Energy: 70 keV to 140 keV) Easy identification of radioisotopes Images obtained without energy differentiation: shows only the radiation intensity distribution Image obtained with 241Am only (Energy: 35 keV to 70 keV) The output data of this sensor is the number of radiation photons differented with five comparators in each detection element. The display in color is construction as for this number of photons. RADIATION LINE SENSOR OPERATION Signal pulses from each detector pixel are differentiated by the five comparators according to their energy levels. These signal pulses are then counted by the five counters and output as the number of photon counting pulses.

Light material Heavy material Application 3: Eliminating effect from beam scattering and hardening Images obtained without energy differentiation are subject to effects from scattered rays and beam hardening. These scattered rays and beam hardening can be eliminated by setting the proper energy differentiation levels. ●Sample of aluminum cylinder with a copper, iron, titanium and carbon rods inserted inside the cylinder Fe Cu C Ti Image obtained without energy differentiation (20 keV to 150 keV) Energy-differentiated image (90 keV or higher) Application 4: Gamma-ray and X-ray spectrum measurement Highly detailed spectrum measurements can be made by auto sweep of the comparator levels. ●57Co spectrum measurement Count rate CH32 CH 64 20 30 44 57 71 84 98 111 125 139 152 Energy (keV) CH 56 CH 48 CH 40 CH 32 Detector channel CH 24 CH32 Count rate CH 16 32 48 63 79 94 110 125 141 156 Energy ( keV ) CH 64 CH 56 CH 48 CH 40 CH 32 CH 24 Count rate 20 Count rate X-ray spectrum measurement 20 CH 16 CH 8 40 57 75 92 110 127 144 CH 1 Detector channel CH 8 CH 1 20 53 88 123 Energy (keV) Energy ( keV ) The output data of this sensor is the number of radiation photons differented with five comparators in each detection element.
