Jefferson Lab

Behind every student exploring science is an educator making it happen. This Teacher Appreciation Day, we celebrate teachers who spark curiosity. Our recent, JSAT Teacher Night brought some of our favorite educators together for hands-on STEM activities. Thank you for all you do!

One force binds a galaxy far, far away. Another connects the building blocks of the universe. At Jefferson Lab, scientists explore the strong force to understand how it binds the nucleus and forms matter. May the (strong) force be with you.

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 celebrated 13 @JLab_News innovators who earned 5 new patents in precision instrumentation, environmental radiation monitoring, SRF quality methods and advanced materials processing. Congratulations and thank you for helping sustain a culture of innovation.

Built from what came before. Inspired by what comes next. Happy Earth Day from Jefferson Lab. 🌎

What if a single speck of dust could derail cutting-edge nuclear physics research? Postdoc Fellow Sasha Hryhorenko inspects a custom ceramic RF window for CEBAF. Even a single embedded particle can affect performance, so every component is checked under a microscope before use.

Inside our clean room, SRF Vacuum Systems Engineer Adam Duzik operates a robotic system with 3D vision for SRF cavity assembly. Less contamination. More precision. Stronger performance.

Today, April 15, we’re heading to the @ENERGY National Lab Research SLAM. Our postdoc, Tyler Hague, will represent Jefferson Lab with his talk, “Opposites Annihilate: Accelerating Antimatter to Unlock New Physics.” Tune in at 4 p.m. ET and cheer him on. sites.google.com/lbl.gov/nlrese…

We're putting a unique "spin" on fusion research, fueling efforts to harness the power of the stars for the world’s electrical grid. The project explores a type of fuel treatment, spin polarization, in the extreme conditions of a superheated plasma. jlab.org/news/releases/…

⏱️ 3 minutes. 💡 Big ideas. 🏆 One slide. On April 15, researchers from 17 @ENERGY National Labs take the stage at the #NationalLabSLAM to translate complex science into compelling presentations for policymakers and the public. sites.google.com/lbl.gov/nlrese…

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.

Early career researchers across the U.S Department of @ENERGY National Lab complex are getting ready for the National Research SLAM. We will be represented by postdoctoral researcher Tyler Hague, who will share how antimatter beams could unlock new physics. Stay tuned.

What does a summer at Jefferson Lab look like? Nand Patel spent his as a 2025 @Energy Science Undergraduate Laboratory (SULI) intern in industrial control systems. Join our SULI Application Workshop April 8, 2–3 p.m. ET for tips and info. science.osti.gov/wdts/suli

No commercial cable exists to deliver 500,000 volts inside a vacuum. So we built a workaround: a pressurized SF₆ gas layer inside a ceramic insulator. And it worked. New paper out in Review of Scientific Instruments. pubs.aip.org/aip/rsi/articl…

We're excited to share that our postdoc Tyler Hague is heading to the DOE National Lab Research SLAM with his talk "Opposites Annihilate: Accelerating Antimatter to Unlock New Physics." Congrats Tyler, and good luck!

How do you test whether our best theory of the universe is complete? You measure differences as small as 35 parts per billion. Jefferson Lab physicist Ciprian Gal earned a @ENERGY Early Career Award to lead precision measurements in the MOLLER experiment. jlab.org/news/releases/…

Spring is here. The seasons change, but the science doesn't stop. Not even between beam runs.

Teachers, this one’s for you. Join us April 15 for Teacher Night at Jefferson Lab. Explore 50+ hands-on science activities you can bring straight to your classroom, connect with fellow educators and earn a recertification point. jlab.org/news/releases/…

Happy St. Patrick's Day from all of us at Jefferson Lab! This year, we're celebrating with particles, beams and a little Irish luck. 🍀

Cooper Middle School Team 1 won the 2026 Virginia Regional Middle School Science Bowl hosted here at Jefferson Lab and will advance to the @ENERGY National Science Bowl in Washington, D.C. 📰 jlab.org/news/releases/… 📷 flickr.com/photos/jeffers…
