A Great Deal for American Science

A Feat of American-CERN Engineering

The Large Hadron Collider—the world’s most powerful particle accelerator—is CERN’s flagship program.

It smashes atoms at almost the speed of light, revealing the inner workings of subatomic particles.

US researchers and engineers designed and built crucial portions of the LHC and its four experiments: CMS, ATLAS, ALICE and LHCb. Americans also led critical R&D programs for the High-Luminosity LHC, an upgrade that will dramatically increase the collision rate.

Today, US researchers are shipping Made in America accelerator magnets and detector components to CERN for the HiLumi upgrade.

The US-CERN community

More than 2,100 researchers from US universities and laboratories work on the experiments hosted at CERN.

The experimental collaborations are formed from teams of independent researchers, which include students, postdocs, professors, staff scientists, engineers and technicians. The scientists work together to run the experiments, analyze the data, and refine our understanding of the fundamental laws of physics.

Most American scientists are based at their home institutions in the United States. They build detectors, perform research, and train the next generation of nuclear and particle physicists without ever having to leave American soil.

Every major technological advancement begins with a discovery in physics

Particle physics drives national, regional, and local progress in science and industry and is the catalyst for many technologies in:

  • Superconducting materials
  • Computing
  • Medicine
  • Radiation sensing
  • Cryogenic cooling

A 2026 Economic Impact report estimated that CERN technologies generate roughly $90 million per year in industry revenue.

Economic Benefits

US firms supply critical technology for CERN’s facilities, creating a two-way flow of investment and innovation.

  • CERN has procured more than $310 million from US firms over the past decade.
  • General Electric supplies high-performance magnets and vacuum systems, with technology benefits flowing back to GE’s U.S. facilities.
  • Intel collaborates on parallel processing architecture and has tested whether its AI-imaging chips are viable for use in space.
  • IBM and CERN are developing quantum computing applications to meet CERN’s growing computational needs.
  • Google and Micron are members of CERN Openlab, accelerating the computing technologies needed to manage CERN’s massive data volumes.

CERN and Space Exploration

NASA uses CERN detector technology on the International Space Station to measure radiation in real time. These measurements are critical for the Artemis program and other deep-space missions. The resulting data informs decisions on:

  • Spacecraft shielding
  • Electronics resilience
  • Astronaut exposure over long-duration missions beyond Earth’s magnetosphere.

CERN’s work on particle detection and large-scale distributed computing also shapes how space agencies approach radiation modeling and mission-scale data systems.
