ATLAS Open Data

  1. Resources
  2. ATLAS Open Data

ATLAS Open Data provides open access to collision data and simulated events from ATLAS for educational and research purposes. Resources are available for students of all ages, enthusiastic self-learners, and physics researchers looking for real experience with ATLAS data. Whether you have an hour or a semester, there’s something here for you. Create a simple histogram, write and visualise a particle-physics analysis directly from your internet browser, work through a tutorial application, or explore the full resources to take a deep-dive into the ATLAS analysis framework and re-discover the Higgs boson!

Education and Outreach

Offline Open Data Analysis

ATLAS open data for education and outreach is intended for everyone that wants to learn about particle physics. Whether you are a high school or university student, a teacher or professor, or just someone curious about the workings of the universe, the open data for education is the ideal way to start or continue learning about high energy particle physics from real data used today for research.

We offer:

Research

Online Open Data Analysis

The data for research is data used for analysis internally by the ATLAS collaboration. It’s aimed at scientists interested in a deeper understanding of particle physics, or in the development of new tools and technologies.

The published data includes:

Accessing the Data

Download the Open Data

The data is hosted at the CERN Open Data Portal. All datasets on the portal are shared under a Creative Commons CC0 public domain dedication; the data and software are assigned unique DOI identifiers to make them citable in scientific articles; and software is released under open source licenses. Learn how to access the data. Computing resources and tips are available.

Tutorials and Tools

8 TeV Open Data resources

At the ATLAS Open Data website we offer a wide range of material to use the open data. We offer a histogram analyser, to make analyses with visual tools; jupyter notebooks with physics analyses to find the Higgs or the Z boson; a tutorial on how to visualize datasets using Phoenix, to make event displays; instructions on how to use containers, to follow the internally used analysis software tutorial; and much more.
