Scientists Piece Together the Largest U.S.-Based Dark Matter Experiment

What if Dark Matter is Lighter? Report Calls for Experiments to Broaden the Hunt

Dark Matter Day Q&A with Berkeley Lab Physicist Quentin Riffard

Quentin Riffard, a project scientist for the LUX-ZEPLIN dark matter detection experiment that is now being installed at the Sanford Underground Research Facility in Lead, South Dakota, shares his experiences in researching dark matter in this Q&A.

Dark Matter Experiments Central Component Takes a Deep Dive

Last week, crews at the Sanford Underground Research Facility (SURF) in South Dakota strapped the central component of LUX-ZEPLIN (LZ) the largest direct-detection dark matter experiment in the U.S. below an elevator and s-l-o-w-l-y lowered it 4,850 feet down a shaft formerly used in gold-mining operations.

DESI Opens Its 5,000 Eyes to Capture the Colors of the Cosmos

The first test of the Dark Energy Spectroscopic Instrument, known as DESI, with its nearly complete complement of components. The long-awaited instrument is designed to explore the mystery of dark energy, which makes up about 68 percent of the universe and is speeding up its expansion.

The Little Computer Cluster That Could

Internship Paves Path to Quantum-Computing Project

Projects like this prove to the skeptics that this idea of quantum computing for particle physics is not so crazy. Its more practical than you think. We now have quantum machines and they work; theyre just pretty noisy. When you try to make them more powerful, thats an issue.
