快中子共振成像实验研究

Experimental Study of Fast Neutron Resonance Radiography

摘要: 利用两次成像法对快中子共振成像进行研究。分别利用6.3 MeV和6.1 MeV快中子对石墨、铜、铝构成的样品进行成像，经图像处理后，消除铜和铝的影像而获得了碳元素的分布图像。

Abstract: The experimental research of fast neutron resonance radiography (FNRR) was carried out with an ‘on-off resonance peak’ method. With the neutrons of 6.3 MeV and 6.1 MeV, fast neutron radiographs of a sample made of graphite, copper, and aluminum were taken. The carbon distribution map was derived from these radiographs, and the figures of copper and aluminum structures were clearly removed.
