Conventional muography detectors are often expensive and not accessible for use by high school students. In this study, we developed a low-cost two-dimensional detector, “SAKURA,” for muography applications, with a total cost of approximately 100,000 JPY. A performance evaluation was conducted at CERN, where we quantitatively assessed the spatial resolution of SAKURA by comparing its output with that of a drift wire chamber (DWC). Visualization of the SAKURA data itself demonstrated its practical potential. The results showed spatial resolutions of 1.3 cm in the x-direction and 0.8 cm in the y-direction. A systematic deviation was observed in the y-direction. To improve the detector design and obtain more detailed resolution measurements, a follow-up experiment is planned at J-PARC in May 2025.
