Abstract

The energy-resolved neutron imaging system, RADEN, has been installed at the pulsed neutron source in the Materials and Life Science Experimental Facility of the Japan Proton Accelerator Research Complex. In addition to conventional neutron radiography and tomography, RADEN, the world's first imaging beam-line at a pulsed neutron source, provides three main options for new, quantitative neutron imaging techniques: Bragg-edge imaging to visualize the spatial distribution of crystallographic information, resonance absorption imaging for elemental composition and temperature information, and polarized neutron imaging for magnetic field information. This paper describes the results of characterization studies of the neutronic performance and installed devices at RADEN and shows the results of several demonstration studies for pulsed neutron imaging.

摘要

能量分辨中子成像系统RADEN已安装在日本质子加速器研究中心材料与生命科学实验设施的脉冲中子源处。除了传统的中子射线照相术和断层扫描术外，RADEN作为世界上首个位于脉冲中子源处的成像束线，为新型定量中子成像技术提供了三种主要选择：用于可视化晶体学信息空间分布的布拉格边缘成像、用于获取元素组成和温度信息的共振吸收成像，以及用于获取磁场信息的极化中子成像。本文描述了RADEN中子性能和已安装设备的特性研究结果，并展示了几项脉冲中子成像示范研究的结果。
