The effort to construct GRETA, a cutting-edge spherical array of high-purity germanium crystals that will measure gamma-ray signals to reveal new details about the structure and inner workings of atomic nuclei, has received key approvals needed to proceed toward full build-out.
New U.S. Department of Energy funding totaling $18 million, including $1 million for user support, will be distributed among 10 partner institutions – including Berkeley Lab – and will continue and expand LaserNetUS operations for three years.
Researchers at Berkeley Lab played a key role in an analysis of data from the world’s largest particle collider that found proof of rare, high-energy particle interactions in which matter was produced from light.
The Large Hadron Collider transforms matter into energy and then back into different forms of matter. But on rare occasions, it can skip the first step and collide pure energy – in the form of electromagnetic waves. Now, scientists have discovered particles of light merging and transforming into W bosons, confirming that at high enough energies, forces that seem separate in our everyday lives are united.
U.S. Department of Energy awards announced in July will advance Lawrence Berkeley National Laboratory (Berkeley Lab) R&D to develop a more effective and compact particle-beam system for cancer treatment, improve particle-beam performance using artificial intelligence, and develop a high-power, rapid-fire laser system for both tabletop and large-scale applications.
Nobel laureate Ernest Lawrence – founder of Berkeley Lab, inventor of the cyclotron, and a native of Canton, South Dakota – will be honored with a memorial highway in his home state.
Today, the hard X-ray system for LCLS-II achieved “first light,” demonstrating its performance in readiness for the experimental campaigns ahead. Berkeley Lab oversaw the construction and delivery of the powerful magnetic components, called undulator segments, for the hard X-ray system.
While COVID-19 risks had led to a temporary halt in fabrication work on high-power superconducting magnets built by a collaboration of three U.S. Department of Energy national labs for an upgrade of the world’s largest particle collider at CERN in Europe, researchers at Berkeley Lab are still carrying out some project tasks.
In a multiyear effort involving three U.S. national laboratories, researchers have successfully built and tested a powerful new focusing magnet that represents a new use for niobium-tin, a superconducting material. The eight-ton device – about as long as a semitruck trailer – set a record for the highest field strength ever recorded for an accelerator focusing magnet, and raises the standard for magnets operating in high-energy particle colliders.
The international Muon Ionization Cooling Experiment (MICE) collaboration, a U.K.-based effort that includes researchers at Berkeley Lab, has made a major step forward in the quest to create an accelerator for subatomic particles called muons.
