Abstract

The Silicon-On-Insulator PIXel (SOIPIX) detector is a unique monolithic structure imaging device currently being 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 $\mathrm{\mu m^{2}}$, 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) application to the optics of an X-ray zooming microscope using two Fresnel zone plates at PF AR-NE1A; (2) application to a phase-contrast X-ray imaging system using a two-crystal X-ray interferometer at the PF BL-14C beamline; and (3) application to nondestructive detection of lithium in Li-ion battery electrode materials using muonic X-rays at J-PARC MLF Muon D2.
