微图案气体探测器(MPGD)具有计数率高、质量轻、耐辐照、位置分辨率好等优点,是一种很有前途和竞争力的热中子成像技术。为了进一步提高空间分辨率,可以采用中子转换径迹的顶点重建。此外,伴随的γ射线背景也对探测器性能有显著影响。在这项工作中,一个热中子探测探测器的基础上,GEM开发,与B4C涂层的聚酯薄膜作为转换器。在此基础上,利用每个信号的信息进行轨迹重建和顶点校正。利用上升时间和能量进一步提高了航迹重构的效果。最后,空间分辨率从1.01 mm显著提高到0.23 mm,用于热中子探测。
Micro Pattern Gaseous Detector (MPGD) is a promising and competitive technology for thermal neutron imaging, due to its many advantages such as high counting rate, low mass, irradiation resistance, and excellent position resolution. In order to further improve spatial resolution, a vertex reconstruction of neutron conversion tracks can be employed. Moreover, the accompanying γ-ray background also has a significant impact on the detector performance. In this work, a detector for thermal neutron detection was developed based on GEMs, with a B4C-coated Mylar foil as the converter. Track reconstruction and vertex correction were achieved with additional use of the information of each signal. The rising time and energy were utilized to improve the track reconstruction furthermore. Finally, the spatial resolution was improved to 0.23 mm from 1.01 mm significantly for thermal neutron detection.
