摘要
利用MCNP模拟,探究探测器所处角度、点源距离和探测器距离三者对中子散射计数与油垢厚度响应关系的影响.模拟结果表明:探测器置于135°角时散射中子计数对油垢厚度的响应关系最明显(灵敏度最高).点源距离和探测器距离越近,散射中子计数对油垢厚度的响应关系越明显.
In this article, The MCNP was used to simulate the change of response relation between scattered neutron counts and grease stain thickness when the angle of detector or the distance of source or the distance of detector was changed. The result of simulation indicates that the sensibility is highest when the angle of detector is 135°,and the sensibility rises when the distance of source or the distance of detector is shortened.
