The objective of this research is to investigate boron carbide diode-based sensors applied to high spatialresolution neutron imagers. The approach is to experimentally and theoretically investigate theoperational parameters and spatial resolution enhancement techniques required for this purpose. Thefour spatial resolution enhancement techniques to be investigated include threshold discrimination,density gradient, fast logic, and columnar sensor medium techniques. Each of these enhancementtechniques will be investigated for feasibility and effectiveness. Boron carbide diode sensors will also becharacterized experimentally with respect to related operational parameters for these spatial resolutionenhancement techniques. The combination of these results will provide a basis for the development of astate-of-the-art neutron imager. The boron carbide will also be tested through direct coupling with TimepixQTPX-262k to test its functionality and improvement of current state of the art techniques utilizingestablished front end electronics and signal processing methods.

本研究的目的是研究应用于高空间分辨率中子成像仪的碳化硼二极管传感器。其方法是从实验和理论上研究实现这一目的所需的操作参数和空间分辨率增强技术。将研究的四种空间分辨率增强技术包括阈值分辨技术、密度梯度技术、快速逻辑技术和柱状传感器介质技术。将对每一种增强技术的可行性和有效性进行调查。碳化硼二极管传感器还将针对这些空间分辨率增强技术的相关操作参数进行实验表征。这些结果的结合将为发展最先进的中子成像仪提供基础。碳化硼还将通过直接与TIMEPEPXQTPX-262K耦合进行测试，以测试其功能以及利用已建立的前端电子学和信号处理方法对当前最先进技术的改进。
