ATLAS Open Data

ATLAS Logo

High Energy Physics data for everyone.

For Education 🎓

To provide data and tools to high school, undergraduate and graduate students, as well as teachers and lecturers, to help educate them and exercise in physics analysis techniques used in experimental particle physics.

For Research 🔬

To provide researchers with high-quality data recorded by the ATLAS detector, enabling them to conduct state of the art analyses in particle physics.

Our values

The collaboration shares the data gathered by the ATLAS detector committing to three fundamental principles:

Accessibility 🌐

Make the data and the tools openly available for everyone to use, without technology, region, or knowledge restrictions.

Transferable expertise 🧠

Along with particle physics analysis and ATLAS learning objectives, provide skills in programming, software and machine learning.

Usability 🛠️

Different target audiences, with different backgrounds and skills must be able to use the data and tools for a wide range of learning objectives.
