摘要
利用MATLAB软件模拟了核裁军核查领域中用于核部件认证的中子计数截断成像方法的处理流程,研究了该方法的有效性和入侵性。通过引入截断矩阵,使该方法具备了通过调节截断参数改变入侵性的能力。数值模拟结果表明,通过限制探测器计数方式,可以在满足认证结果有效的同时,降低主动中子成像技术的入侵性。
The process of truncated neutron imaging method to identify the uniformity of nuclear components for nuclear reduction verification is simulated by using Matlab.Based on the simulation tool,the validity and intrusiveness of the method are studied.With introduction of truncated matrix,the method is endowed with capability of changing its intrusiveness by the selected truncated parameters.Simulation results indicate that,by restricting the counting method,it is possible to reduce the intrusiveness of neutron imaging technology and satisfy the validity of the authentication.
