Abstract Scanning/transmission electron microscopy (STEM) is a powerful characterization tool for wide range of materials. Over the years, STEMs have been extensively used in situ studies structural evolution and dynamic processes. A limited number STEM instruments are equipped with secondary (SE) detector addition to conventional transmitted detectors, i.e. bright-field (BF) annular dark-field (ADF) detectors. Such capable simultaneous BF-STEM, ADF-STEM SE-STEM imaging. These methods can...
The high granularity of the CALICE Semi-Digital Hadronic CALorimeter (SDHCAL) provides capability to reveal track segments present in hadronic showers. These are then used as a tool probe behaviour active layers situ, better reconstruct energy these showers and also distinguish them from electromagnetic ones. In addition, comparison data simulation helps discriminate among different shower models simulation. To extract recorded SDHCAL, Hough Transform is after being adapted presence dense...
