Deep Underground Neutrino Experiment (DUNE) is a leading-edge physics experiment designed to study neutrinos, one of the most elusive particles in the universe. By constructing massive liquid argon time projection chambers deep underground, DUNE aims to detect neutrinos from various sources, including those produced by cosmic events, to unravel mysteries about neutrino properties, matter-antimatter asymmetry, and the physics of the early universe.

Goals

• Measure neutrino oscillation parameters with high precision.
• Search for CP violation in the lepton sector to explain matter dominance.
• Detect neutrinos from supernovae and other cosmic sources to study astrophysical phenomena.

Organization

DUNE is managed by the Office of High Energy Physics within the U.S. Department of Energy's Office of Science. It's a collaborative effort primarily between Fermilab in the U.S. and CERN in Europe, with international contributions from over 30 countries. The project is overseen by a co-spokesperson system, with significant involvement from DOE labs, universities, and funding from multiple agencies.

The leadership roles are held by **Co-spokespersons** of the DUNE collaboration.

Partners

• No specific partnerships are listed, but DUNE involves a broad international collaboration, including:
• Fermi National Accelerator Laboratory
• CERN

History

DUNE was officially launched in 2014, succeeding the Long-Baseline Neutrino Experiment (LBNE). It has progressed from conceptual design to construction, with significant milestones like the start of excavation at the Sanford Underground Research Facility (SURF) in South Dakota for the far detector. Key events include the installation of the first detector module and the commencement of the first physics data collection with the near detector at Fermilab. The experiment is expected to yield results into the 2030s.

Funding

The total cost for DUNE has not been publicly itemized, but it involves significant investments from the DOE, NSF, and international partners. The DOE has committed hundreds of millions of dollars, with additional funding for construction, operation, and research.

Implementation

Implementation involves:

• Construction of the neutrino beam at Fermilab and detectors at both near and far sites.
• Development and deployment of liquid argon time projection chambers for neutrino detection.
• Ongoing international collaboration for data analysis and scientific interpretation.

DUNE's data collection phase is expected to extend into the 2030s, representing a long-term commitment to neutrino physics.
