Description

As an important supplement to existing technologies such as X-ray and neutron imaging, muon (μ) tomography technology has been widely studied in interdisciplinary fields such as natural disaster early warning, mineral exploration, geology, and archaeology. Muon track detection based on MPGD is one of the important technical solutions for high-resolution muon imaging research. The research team at USTC has long been committed to the research of large-area high-resolution detectors and their readout electronics, and has built several μSTC (muon Scattering tomography and Transmission imaging faCility) prototypes for muon imaging research. In this talk, we will present the lastest developments on the muon detectors and muography study, Micromegas detectors with large area of 400 mm×400 mm to 600 mm×600 mm were achieved, and high spatial resolution of better than 150 μm and detection efficiency of higher than 95% were validated by cosmic ray test. The μSTC prototypes was used to explore the possible internal structure of Dashu Mountain, a 60-million-year-old ancient volcano. Another interesting attempt is the imaging study of iron-making blast furnaces, related results will also be reported.
