| 内容記述 | There is some possibility that many granular regions which have a Cl density approximately one order of magnitude higher than their surrounding region are distributed and have an extremely lower resistivity in high resistivity CdTe(Cl). When high resistivity CdTe(Cl) is used as a radiation detector, these granular regions behave almost like a metal and become dead regions. Measurements by the photon counting method showed that the CdTe(Cl) detector volume ratio includes approximately 15 % dead regions. Assuming that the dead regions are distributed as many granular conductor particles in the CdTe(Cl) detector, calculations showed that the practical electric thickness of the CdTe(Cl) detector is reduced to approximately 45 % of the real thickness. The characteristic of the response function of the CdTe(Cl) detector calculated using this electric thickness give good agreement with that given by the measured spectrum curve. This good agreement strongly supported the followings that approximately 15 % of the total volume is distributed as conductor particles, becoming dead regions and reducing the electric thickness to approximately 45 % in the CdTe(Cl) detector. | |||||
