摘要：
硅基绝缘体像素（SOIPIX）探测器是一种独特的单片结构成像器件，目前由KEK领导的SOIPIX小组开发。KEK光子工厂（PF）的探测器团队已开发出基于INTPIX4NA SOIPIX探测器的X射线相机。该探测器具有14.1×8.7 mm²的敏感区域，425,984个像素排列成832列×512行矩阵，像素尺寸为17×17 μm²，提供高空间分辨率和低强度X射线条件下的优异灵敏度。X射线相机使用的读出系统由PF开发，配备SiTCP-XG，一种基于现场可编程门阵列实现的10Gb以太网网络控制器，可实现数百赫兹的高帧率成像。目前，我们正在研究该X射线相机在KEK多个实验中的适用性。本文报告了三项近期应用研究：（1）使用两个菲涅尔区板的X射线放大显微镜光学系统在PF AR-NE1A；（2）使用双晶体X射线干涉仪的相位对比X射线成像系统在PF BL-14C；（3）使用μ子X射线在J-PARC MLF Muon D2中非破坏性检测锂离子电池电极材料中的锂。
英文摘要：
The Silicon-On-Insulator PIXel (SOIPIX) detector is a unique monolithic structure imaging device currently being developed by the SOIPIX group, led by the High Energy Accelerator Research Organization (KEK). Our detector team at the KEK Photon Factory (PF) has developed an X-ray camera based on the INTPIX4NA SOIPIX detector. This detector provides a sensitive area of 14.1 $\times$ 8.7 $\mathrm{mm^2}$, with 425,984 pixels arranged in an 832-column $\times$ 512-row matrix and a pixel size of 17 $\times$ 17 $\mathrm{μm^{2}}$, and offers high spatial resolution and excellent sensitivity under low-intensity X-ray conditions. The readout system used in the X-ray camera is developed at the PF. It is equipped with SiTCP-XG, a 10 Gb Ethernet network controller implemented on a field-programmable gate array, enabling high-frame-rate imaging at several hundred hertz. We are currently investigating the applicability of this X-ray camera in several experiments at KEK. Herein, we report three recent application studies: (1) X-ray zooming microscope optics using two Fresnel zone plates at PF AR-NE1A; (2) phase-contrast X-ray imaging system using a two-crystal X-ray interferometer at PF BL-14C; and (3) nondestructive lithium detection in Li-ion battery electrode materials using muonic X-rays at J-PARC MLF Muon D2.
