One of the DUNE near detector's subdetectors, SAND, will detect neutrinos with an electronic calorimeter, which measures particle energy, and a tracker, which records particle momenta and charge. A second subdetector will use liquid argon to mimic the neutrino interactions in the far detector. The third will use gaseous argon. Working together, they will measure particles with more precision than other neutrino detectors have been able to achieve. Credit: DUNE collaboration

Particle detector at Fermilab plays crucial role in Deep Underground Neutrino Experiment

DUNE’s near detector, located at Fermilab, will take vital measurements of neutrino beam energy and composition before it reaches the experiment’s far detector in South Dakota. Its unmatched precision measurements will offer its own opportunities for the discovery of new physics.

Precision measurements of intracluster light suggest possible link to dark matter

Faint light from rogue stars not bound to galaxies has been something of a mystery to scientists. The dimness of this intracluster light makes it difficult to measure, and no one knows how much there is. Scientists on the Dark Energy Survey, led by Fermilab, have made the most radially extended measurement of this light ever and have found new evidence that its distribution might point to the distribution of dark matter.

Robert Bernstein still relishes challenge in second stint as Mu2e co-spokesperson

Bernstein is overseeing the Fermilab Mu2e experiment as it moves from its construction to installation phase and into a running experiment. A collaboration of nearly 250 scientists at 40 institutions that had to invent technology to get to this point, Mu2e is in an exciting phase, especially for early-career researchers who will not only construct the experiment, but also analyze the data.

Northern Illinois flourishes as accelerator R&D hub under Fermilab leadership

Fermilab and partners in northern Illinois have established the region as a leader in particle accelerator science and technology. Few places in the world boast such a concentrated effort in particle acceleration research, developing and building cutting-edge particle accelerators, and growing an accelerator-focused workforce.

Fermilab oil spill cleanup technology among finalists for R&D 100 Award

What began as an experiment in a nine-ounce cup of water has been developed into a full-scale technology that recently became a finalist for a 2019 R&D 100 Award. Achieving the honor was E-MOP™ — electromagnetic oil spill remediation technology — developed from patents owned by Fermilab. The technology uses materials that are environmentally safe, reusable and natural.

Cosmic-muon detector technology earns R&D 100 Award for Fermilab and its partners

The new technology is a miniaturized version of a sensor developed for the CMS experiment at the Large Hadron Collider. But instead of being used for discovery science, the sensors are developed to screen cargo by detecting muons, particles that penetrate materials such as concrete and lead. Scientists at Fermilab, Los Alamos National Laboratory and the Nevada National Security Site designed, assembled and tested the small, slim sensors, which could replace bulkier screening technologies.
