We have developed a neutron imaging sensor based on an INTPIX4-SOI pixelated silicon device. Neutron irradiation tests are performed at several neutron facilities to investigate sensor’s responses for neutrons. Detection efficiency is measured to be around 1.5% for thermal neutrons. Upper bound of spatial resolution is evaluated to be $4.1\pm 0.2\mathrm{\mu }\mathrm{m}$ in terms of a standard deviation of the line spread function.

使用INTPIX4-SOI像素化硅器件开发中子成像传感器

我们已经开发了一种基于INTPIX4-SOI像素化硅器件的中子成像传感器。在几个中子设施中进行中子辐照测试，以调查传感器对中子的响应。据测量，热中子的探测效率约为1.5％。空间分辨率的上限被评估为$4。\mathrm{1个}\pm 0。2\mathrm{\mu }\mathrm{米}$ 根据线扩散函数的标准偏差。
