Most Precise Measurement of Energy Range for Particles Produced by Nuclear Reactors Reveals Surprises

An international team that includes researchers from Berkeley Lab has captured the most precise—and puzzling—energy measurements yet of ghostly particles called reactor antineutrinos produced at a nuclear power complex in China.

Coupling 2 ‘Tabletop’ Laser-Plasma Accelerators, a Decisive First Step Toward Tomorrow’s Ultrapowerful Compact Machines

Scientists at Berkeley Lab’s BELLA Center demonstrated that a laser pulse can accelerate an electron beam and couple it to a second laser plasma accelerator, where another laser pulse accelerates the beam to higher energy—a fundamental breakthrough in advanced accelerator science.

Best Precision Yet for Neutrino Measurements at Daya Bay

In the Daya Bay region of China a research project is underway to study ghostlike, elusive particles called neutrinos. Today, the international Daya Bay Collaboration announces new findings on the measurements of neutrinos, paving the way forward for further neutrino research, and confirming that the Daya Bay neutrino experiment, significant as the first equal partnership between the U.S. and China in a major physics project, continues to be one to watch.

Fortifying Computer Chips for Space Travel

Berkeley Lab’s particle accelerator blasts microprocessors with high-energy beams to toughen them up for trips into low-earth orbit and beyond.

New Visitor Center in South Dakota Highlights Underground Science

The Sanford Lab Homestake Visitor Center, a facility that highlights Homestake Mine’s gold and silver past and particle physics future, held its grand opening ceremony on June 30.

For Ultra-cold Neutrino Experiment, a Successful Demonstration

An international team of nuclear physicists announced the first scientific results from the Cryogenic Underground Observatory for Rare Events (CUORE) experiment. CUORE is designed to confirm the existence of the Majorana neutrino, which scientists believe could hold the key to why there is an abundance of matter over antimatter.

U.S. Scientists Celebrate the Restart of the Large Hadron Collider

With the collider back in action, the more than 1,700 U.S. scientists who work on LHC experiments are prepared to join thousands of their international colleagues to study the highest-energy particle collisions ever achieved in the laboratory.

What to Expect Next from the World’s Largest Particle Accelerator

Berkeley Lab researchers, Beate Heinemann and Peter Jacobs were on a recent panel of scientists that discussed the scientific implications of this new and improved accelerator.

Dynamic New App for Learning About Particle Physics Now Available

A free app for Android and Apple devices called The Particle Adventure makes checking out the world of quarks, dark matter, and particle accelerators as easy as tapping touchscreen icons. The science of particle physics is illustrated via categories including “How Do We Know Any of This?” and “Unsolved Mysteries.” You can skim through the major categories or dig deep into topics such as the discovery of the Higgs boson.

A Closer Look at the Perfect Fluid

By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, “perfect fluid” that give clues to the state of the young universe just microseconds after the big bang.
