Attention Hampton Roads: We will be conducting our monthly tornado siren test at 10:30 a.m. today. Residents within 1.5 miles of the laboratory may hear the siren. This is only a test. No need to take cover if you hear it.

We are proud to announce the appointment of Fernanda G. Garcia as Associate Laboratory Director for CEBAF. This newly created role reflects our commitment to scientific discovery and operational excellence.

Fernanda's distinguished career across some of the nation's most prestigious national laboratories makes her the ideal leader to guide CEBAF into its next chapter, and we are honored to have her on board.

Nuclear Physicists Discover New Rule for Peppy Partner Picking This schematic of the reaction shows an electron (purple) scattering from a nucleus by emitting a (purple) virtual photon, which knocks out a proton (blue).

Today, SURATech officially assumed management and operating responsibilities for Jefferson Lab.

This marks a new chapter as we advance toward becoming a multipurpose national laboratory focused on delivering groundbreaking science and exceptional operations in service of the DOE and the nation.

Jefferson Lab Begins New Era Under SURATech Leadership Transition ensures the lab will seamlessly continue to advance its science and technology mission NEWPORT NEWS, VA – Effective today, SURATech has officially assumed management and operating responsibilities for the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility, mar...

Jefferson Lab staff members rolled out the welcome mat for student participants of our summer programs, including undergraduates in our workforce development for teachers and scientists internship programs and graduate students in the Christopher Newport University Graduate Summer Workshop in Nuclear and Hadronic Physics (CNUGS) the best way we know how — by repping our college gear! CNUGS continues a long tradition of advanced training in nuclear and hadronic physics while bringing fresh energy with AI, machine learning, and data science.

The LEAD Virginia Class of 2026 stopped by Jefferson Lab this past week for a front-row look at the cutting-edge science shaping our world.

Our Deputy Chief Operating Officer, Natalie Carter, gave the group an inside look at how we're exploring the mysteries of protons, neutrons, and atomic nuclei.

Jefferson Lab will be closed Monday, May 25, in observance of Memorial Day.

While summer temperatures climb across Hampton Roads, parts of CEBAF operate at temperatures colder than deep space.

Our cryogenics team helps operate and maintain the systems that keep CEBAF’s superconducting accelerator cavities near 2 kelvin, or nearly -456°F. These ultra-cold conditions allow the accelerator to operate efficiently, supporting research and scientific discovery at Jefferson Lab.

Thirty years ago today, the City of Newport News broke ground on the Applied Research Center. Today, the ARC is undergoing a renovation to modernize the building for its future as a cornerstone of the Jefferson Lab campus.

When matter meets antimatter, both disappear in a burst of energy. Jefferson Lab researcher Tyler Hague is studying how that reaction could help scientists make more precise nuclear physics measurements.

At Jefferson Lab, postdoctoral researcher Tyler Hague is exploring how positrons, the antimatter counterparts to electrons, could help scientists make some of the most precise nuclear physics measurements ever attempted.

That work recently took him to Capitol Hill, where he represented us at the 2026 National Lab Research SLAM alongside researchers from all 17 U.S. Department of Energy national laboratories.
