1. 高产额中子源及其应用

高产额的中子源对于中子在医学治疗(BNCT)、科学研究(中子散射)和工业无损检测(中子照相)等领域的应用是至关重要的。从目前的发展现状来看,基于低能加速器(不诱发散裂反应)的强流中子源技术仍然未解决的难题。我的研究重点之一,即在于探索基于光核反应的长寿命、高产额(>1E13n/s)中子源实现方法。

2. 中子应用技术研究

⑴ 新一代无损检测技术——基于单电子加速器的中子/光子双模成像技术

与传统的基于X射线的无损检测技术相比,本技术在一个电子加速器的框架下同时实现了X射线成像和中子成像,并将二者的信息有效地融合起来,从而不仅可以得到被检测物体的质量厚度信息(传统方法的能力),还能得到被检测物体的物质属性信息(本方法所提供的新能力),将可(不限于)应用于下列领域:

涡轮叶片(航发、汽轮机)残余型芯检测

 

(a) T he photo of an inspected turbine blade; (b) the neutron image and (c) the X-ray image of the blade without gadolinium tracer; (d) the neutron image and (e) the X-ray image of the blade with gadolinium tracer (Measuring time is 60 min for each pair of imaging).

(a) Fused image of the turbine blade; (b) the distributions of μm,n/μm,X for turbine blades with or without gadolinium tracer, for six different positions of the turbine blade (selected region is 40 × 40 pixels); (c)(1) the bivariate histograms for turbine blades with gadolinium tracer and (c)(2) without gadolinium tracer. Pixel density is the number of pixels in the area of 0.0075 μt × 0.0075 μt.
