Acrylic Tanks Provide Clear Window Into Dark Matter Detection

Scientists have a new window into the search for dark matter – an acrylic vessel that features a grouping of 12-foot-tall transparent tanks with 1-inch-thick walls. The tanks, which will surround a central detector for a nearly mile-deep experiment under construction in South Dakota called LUX-ZEPLIN (LZ), will be filled with liquid that produces tiny flashes of light in some particle interactions.

A Quantum Leap Toward Expanding the Search for Dark Matter

Through a new research program supported by the U.S. Department of Energy’s Office of High Energy Physics, a consortium of researchers from Berkeley Lab, UC Berkeley, and the University of Massachusetts Amherst will develop sensors that enlist the seemingly weird properties of quantum physics to probe for dark matter particles in new ways, with increased sensitivity, and in uncharted regions.

A Supercool Component for a Next-Generation Dark Matter Experiment

A large titanium cryostat designed to keep its contents chilled to minus 148 degrees has completed its journey from Europe to South Dakota, where it will become part of a next-generation dark matter detector for the LUX-ZEPLIN (LZ) experiment.

Tiny Distortions in Universe’s Oldest Light Reveal Clearer Picture of Strands in Cosmic Web

Scientists have decoded faint distortions in the patterns of the universe’s earliest light to map huge tubelike structures invisible to our eyes – known as filaments – that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.

Beyond the WIMP: Unique Crystals Could Expand the Search for Dark Matter

A new particle detector design proposed at the U.S. Department of Energy’s Berkeley Lab could greatly broaden the search for dark matter – which makes up 85 percent of the total mass of the universe yet we don’t know what it’s made of – into an unexplored realm.

New Study: Scientists Narrow Down the Search for Dark Photons Using Decade-Old Particle Collider Data

A fresh analysis of particle-collider data, co-led by Berkeley Lab physicists, limits some of the hiding places for one type of theorized particle – the dark photon, also known as the heavy photon – that was proposed to help explain the mystery of dark matter.

Dark Matter Day Is Approaching … but Don’t Be Afraid of the Dark

A global hunt for the universe’s missing matter is underway, and this autumn everyone is invited to join in. On and around October 31, 2017, events around the world will celebrate the hunt for the universe’s unseen “dark matter.”

Next-Gen Dark Matter Detector in a Race to Finish Line

The race is on to build the most sensitive experiment designed to directly detect dark matter particles known as WIMPs. The LUX-ZEPLIN project has formally cleared a key construction milestone that will propel it toward its April 2020 goal for completion.

Planetarium Show Brings ‘Phantom’ Matter to Life

A new planetarium show, produced in part by Berkeley Lab’s Michael Barnett, is designed to immerse audiences in the search for dark matter, which we have so far detected only through its gravitational effects.

World’s Most Sensitive Dark Matter Detector Completes Search

The Large Underground Xenon (LUX) dark matter experiment, which, with the help of Berkeley Lab researchers, operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its search for the missing matter of the universe. At a meeting in the UK, LUX scientific collaborators presented the results from the detector’s final 20-month run.
