- Effect of Fast Neutron Irradiation on C
この論文をさがす
説明
<BR>The influence of fast neutron irradiation was studied for CdTe radiation detectors in the range of fluence 1.0×108-1.8×1011n/cm2. The effect of γ-ray heavy irradiation toward the detector was also investigated for the comparison. Americium-241 and 137Cs γ-ray spectra measured before and after irradiation were compared to examine the change of the detector performance. A pulse height and a rise time of a radiation signal were simultaneously measured in order to evaluate the transport property of both electrons and holes. Peak shift toward lower energies was observed in the 241Am γ-ray spectrum after fast neutron irradiation. Electron μτ product showed large decrease with increasing the neutron fluence, while the one for holes remained unchanged. For the γ-ray irradiation, the spectrum shape of 137Cs changed due to the influence of carrier detrapping. Experimental results support that the electron-trapping center generated by fast neutrons degrades the detector performance of the CdTe detector.
