Brookhaven National Laboratory is the host site for the future Electron-Ion Collider (EIC), a unique high-energy, high-luminosity polarized collider that will be one of the most challenging and exciting accelerator complexes ever built. The EIC will be a discovery machine, providing answers to long-elusive mysteries of matter related to our understanding the origin of mass, structure, and binding of atomic nuclei that make up the entire visible universe.

The EIC Directorate will work closely with domestic and international partners to deliver the $1.6B—$2.6B EIC construction project and then begin EIC operations.

Center for Frontiers in Nuclear Science

The mission of this Center is to promote and facilitate the realization of the U.S. based EIC by enhancing the science case and collaborations amongst the scientists around the world interested in the EIC.

Electron-Ion Collider User Group

The Electron-Ion Collider User Group consists of more than 1,000 physicists from over 200 laboratories and universities from around the world who are working together to make the EIC a reality.

EIC Theory Institute

The mission of the EIC Theory Institute is to broaden our understanding of the scientific possibilities that will be created by the Electron-Ion Collider. A primary goal of the Institute is a vibrant and diverse program of short-term, mid-term and long-term visitors who enrich and complement EIC research at Brookhaven Lab.


The Electron-Ion Collider Center at Jefferson Lab (EIC2@JLab) is an organization to advance and promote the science program at the EIC. Particular emphasis is on the close connection of EIC science to the current Jefferson Lab 12 GeV CEBAF science program.
