轴对称型BGO反康屏蔽探测器研制
Development of an axial symmetry type BGO anti-Compton shield detector
【摘要】 着重报告了自行研制的轴向对称型BGO反康屏蔽探测器的基本结构、抑制原理及其抑制性能的测试结果。测得60Coγ射线源的康普顿抑制系数在能区100~300、300~800、800~1100keV范围内分别为2.3、4.1和4.6,且峰总比为37%(对相对效率为30%的HPGe探测器)。
【Abstract】 The basic structure, the suppression principle and measurement results of the suppressed performance for the axial symmetry type BGO antiCompton shield detector are reported in this paper. The Compton suppression factors (CSF) measured are about 2.3, 4.1 and 4.6 in the energy region of 100~300, 300~800 and 800~1100 keV respectively to γrays from a 60Co source. The peaktototal ratio is about 37%(for the relative efficiency 30% HPGe detector).
