摘要
核武器部件的球对称性是军控核查和深度核裁军中需要重点认证的属性之一。本文应用MonteCarlo方法模拟了高纯锗探测器对特定形状部件的自发γ辐射场的绝对效率分布。模拟计算表明,被动γ谱法可以用于对准球对称性属性的测量。
Sphere symmetry of nuclear weapon, is one of the most significant attributes discussed in arms control verification and nuclear disarmament. In this paper, the absolute detection efficiency distribution of HPGe γ detector in respect to spontaneously gamma radiation field of special shape assembly was simulated by Monte Carlo method. The results of simulation have shown that passive gamma spectroscopy mode could be used in recognizing the symmetric attribute of quasi-sphere.
