With a ceremony held today, Fermilab joined with its international partners to break ground on a new beamline that will help scientists learn more about ghostly particles called neutrinos. The beamline is part of the Long-Baseline Neutrino Facility, which will house the Deep Underground Neutrino Experiment, an international endeavor to build and operate the world’s most advanced experiment to study neutrinos.

Fermilab scientist Alexey Burov has discovered that accelerator scientists misinterpreted a certain collection of phenomena found in intense proton beams for decades. Researchers had misidentified these beam instabilities, assigning them to particular class when, in fact, they belong to a new type of class: convective instabilities. In a paper published this year, Burov explains the problem and proposes a more effective suppression of the unwanted beam disorder.

The Deep Underground Neutrino Experiment will tackle some of the biggest mysteries in physics — and to do so, it will need the most intense high-energy beam of neutrinos ever created. Engineers are up to the complicated task, which will need extreme versions of some common-sounding ingredients: magnets and pencil lead.

Researchers are wielding quantum physics, technologies and expertise to develop a proposed Illinois Express Quantum Network, which would stretch between Fermilab and Northwestern University’s Evanston and Chicago campuses. The metropolitan-scale, quantum-classical hybrid design combines quantum technologies with existing classical networks to create a multinode system for multiple users.

Scientists who moved from particle physics or astrophysics to medical physics sit down with Symmetry to talk about life, science and career changes.

Site preparation work starts at Fermilab this fall for the international Deep Underground Neutrino Experiment. Contractors will begin site prep where the powerful particle beam will be extracted and sent toward its final destination in South Dakota.

Fermilab’s NOvA neutrino experiment records in its giant particle detector the passage of slippery particles called neutrinos and their antimatter counterparts, antineutrinos. Famously elusive, these particles’ interactions are challenging to capture, requiring the steady accumulation of interaction data to be able to pin down their characteristics. With five years’ worth of data, NOvA is adding to scientists’ understanding of neutrinos’ mass and oscillation behavior.

The evolution of one of the most critical components of the Mu2e experiment, the production target, is a testament to the strength of the team putting it together.

Test beams generally sit to the side of full-on accelerators, sipping beam and passing it to the reconfigurable spaces housing temporary experiments. Scientists bring pieces of their detectors — sensors, chips, electronics or other material — and blast them with the well-understood beam to see if things work how they expect, and if their software performs as expected. Before a detector component can head to its forever home, it has to pass the test.

The cryostat for Berkeley Lab’s LUX-ZEPLIN experiment — the largest direct-detection dark matter experiment in the U.S. — is successfully moved to its research cavern. This final journey of LZ’s central detector on Oct. 21 to its resting place in a custom-built research cavern required extensive planning and involved two test moves of a “dummy” detector to ensure its safe delivery.
