An experiment to capture unprecedented 3D images of the trajectories of charged particles has been demonstrated using cosmic rays as they strike and travel through a cryostat filled with a ton of liquid argon. The results confirm the capabilities of a novel detector technology for particle physics.
Berkeley Lab’s contributions span the planning, construction, and data analysis central to the collaboration’s groundbreaking discoveries.
A trio of physicists – including Uroš Seljak of Lawrence Berkeley National Laboratory – has been awarded the 2021 Gruber Cosmology Prize for their work studying the large-scale structure of the universe as well as the properties of its first instant of existence.
The Advanced Light Source, a scientific user facility at Berkeley Lab, has received federal approval for the budget, schedule, and technical scope for a major upgrade project that will boost the brightness of its X-ray beams at least a hundredfold.
A research team co-led by Berkeley Lab has created and observed quasiparticles called 3D hopfions at the nanoscale (billionths of a meter) in a magnetic system. The discovery could advance high-density, high-speed, low-power, yet ultrastable magnetic memory “spintronics” devices.
Scientists at Berkeley Lab have demonstrated how to image samples of heavy elements as small as a single nanogram. The new approach will help scientists advance new technologies for medical imaging and cancer therapies.
Researchers have channeled the universe’s earliest light – a relic of the universe’s formation known as the cosmic microwave background (CMB) – to solve a missing-matter mystery and learn new things about galaxy formation. Their work could also help us to better understand dark energy and test Einstein’s theory of general relativity by providing new details about the rate at which galaxies are moving toward us or away from us.
The U.S. Department of Energy has formally approved a key milestone in the High-Luminosity LHC Accelerator Upgrade Project being carried out at eight U.S. institutions, including the DOE’s Berkeley Lab.
The events following the Fukushima disaster, a decade ago, drew upon Berkeley Lab’s long-standing expertise in radiation measurements and safety, and led to the creation of long-term radiation-monitoring programs, both locally and in Japan, as well as a series of radiation surveys and technology demonstrations including drone- and helicopter-based surveys, and vehicle-based and hand-carried measurements.
A new analysis of collisions conducted at different energies, with contributions by Berkeley Lab scientists, shows tantalizing signs of a critical point – a change in the way that quarks and gluons, the building blocks of protons and neutrons, transform from one phase to another.
