摘要

用MCNPX蒙特卡罗程序设计并模拟了一种利用中子发射10MeV电子直线加速器的热中子照相装置。该设施针对准直器比率L/D的广泛值范围进行，该比率是描述所产生的射线照相图像质量的主要参数。结果表明，该装置具有较高的热中子通量；而使用单个蓝宝石滤光片满足了表征高质量热中子射线照相系统的所有建议值。与其他类似设施的比较表明，使用10MeV电子束的光中子源是射线照相目的的有用替代品。

Development of a Neutron Radiography System based on a 10 MeV Electron Linac

A thermal neutron radiography unit using the neutrons which emits a 10 MeV electron linac compact has been designed and simulated via MCNPX Monte Carlo code. The facility was carried out for an extensive range of values for the collimator ratio L/D, the main parameter which describes the quality of the produced radiographic images. The results show that the presented facility provides high thermal neutron flux; while with the use of single sapphire filter fulfills all the suggested values which characterize a high quality thermal neutron radiography system. A comparison with other similar facilities indicates that the use of a photoneutron source using a 10 MeV electrons beam is a useful substitutional for radiographic purposes.
