ATLAS Masterclass
- Masterclasses
Students learn about particle physics and the ATLAS detector at the ATLAS Masterclasses. This is the largest particle detector ever built at an accelerator. It is used to detect the smallest building blocks of our matter, which interact in a variety of ways in high-energy collisions. The reconstructed tracks can be used to draw conclusions about the processes in the collisions, allowing interesting physical processes to be identified and studied in more detail. Most recently, the ATLAS experiment has been the talk of the town with the discovery of the Higgs boson. In addition to more detailed investigations of the Higgs boson, parameters of the Standard Model are measured and clues to new physical phenomena are sought.



![3D visualisation of human neuronal tissue reconstructed by multi-scale X-ray phase contrast tomography. Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
