Description
Since 2020, National Central University and Academia Sinica have spearheaded the inaugural muography program in Taiwan.
The detector utilizes a SiPM-coupled plastic scintillator design with a pixelated readout system, optimized for precise particle tracking.
The collaboration has completed two initial R&D phases to optimize detector performance and data analysis frameworks. These efforts have culminated in the
current large-scale geophysical survey of Mt. Qixing, the prominent peak of the Tatun Volcanic Group.
As one of the highest peaks in the Tatun Volcanic Group, the internal density structure of Mt. Qixing remains a
subject of great interest to the Earth Science community in Taiwan. Our objective is to generate the first 3D density reconstruction of
the mountain using muography. The project utilizes three observatories strategically positioned around the peak. The first observatory,
located on the southeast flank, began stable data acquisition in late 2025. We are currently deploying a second observatory opposite the first
to provide the cross-sectional data necessary for a more precise multi-directional density measurement. This poster presents the setup and preliminary
results for the first observatory. It also highlights the construction status of the second observatory and our future agenda.
