High-Luminosity ATLAS

Higgs boson candidate

What is High-Luminosity ATLAS?

The High-Luminosity phase of the Large Hadron Collider (HL-LHC), set to begin in 2030, will deliver roughly an order of magnitude more data than previous runs. This unprecedented dataset will enable precision measurements of the Higgs boson’s properties and enhance sensitivity to a wide range of new-physics scenarios. To study this wealth of data, the ATLAS Collaboration is undertaking major detector upgrades that incorporate state-of-the-art technologies. HL-ATLAS will include a completely new inner tracker, a high-granularity silicon timing detector, and enhancements to the trigger and data-acquisition systems.

ATLAS Visits

How to visit in person

To schedule an onsite visit to the ATLAS experiment, please contact the CERN Visits Service.

The ATLAS Visitor Center has a permanent exhibit with interactive screens outside the Control Room and a 3D movie which explains how the detector works and why the collaboration pursues its quest for fundamental knowledge. CERN also has two permanent exhibitions Universe of Particles and Microcosm that provide unique experiences in understanding the secrets of matter and exploring the mysteries in our universe.

ATLAS Virtual Visits

How to visit remotely

An ATLAS Virtual Visit connects a classroom, exhibition or other public venues with scientists at the experiment using web-based video conferencing. It is a chance for you to have a conversation with the scientists working on ATLAS.

Group Visits

For groups of at least 10 visitors, you can schedule a Virtual Visit by completing this form.

ATLAS Virtual Tours

Explore ATLAS virtually

Take a virtual tour around the ATLAS detector in the cavern, located around 80 meters below ground at interaction point 1 of the LHC. Alternatively, walk around the detector and control room using Google's street view.
