Ten international funding agencies will contribute to the construction of the gigantic particle detectors a mile underground for the Fermilab-hosted Deep Underground Neutrino Experiment.
Batavia, Illinois, Dec. 06, 2023 (GLOBE NEWSWIRE) — The Deep Underground Neutrino Experiment — also known as DUNE — is an international mega science experiment that will use enormous particle detectors to study the behavior of neutrinos, which might indicate why we live in a matter-dominated universe.
The DUNE collaboration, representing scientists from dozens of countries around the world, will contribute to the construction of detectors at two sites in the United States: one at the U.S. Department of Energy’s Fermi National Accelerator Laboratory, the host lab for DUNE, 40 miles west of Chicago, and the other at the Sanford Underground Research Laboratory (SURF) in Lead, South Dakota.
On Nov. 17, representatives of funding agencies from five countries signed a memorandum of understanding, affirming their commitment to contribute to the construction of components for DUNE. Director Lia Merminga signed on behalf of Fermilab.
“DUNE will help answer some of the biggest questions in the universe and has the potential to transform the field of neutrino physics. We are proud to host DUNE in the U.S. with major contributions from the project’s international partners who offer their unique expertise,” said Regina Rameika, DOE associate director for the Office of High Energy Physics. “Having the commitment from our international partners to contribute these vital components is an essential aspect of DUNE.”
With their signatures, University of Campinas (Unicamp), Brazil, Institut National de Physique Nucléaire et de Physique des Particules (IN2P3), France, Istituto Nazionale Di Fisica Nucleare (INFN), Italy, University of Bern, Switzerland, and the Science and Technology Facilities Council/United Kingdom Research and Innovation (STFC/UKRI), United Kingdom, committed to contributing hardware to the two DUNE Far Detectors in South Dakota.
The Canadian Foundation for Innovation John R. Evans Leaders Fund and the Ontario Research Fund in Canada in addition to CERN in Switzerland also signed the memorandum of understanding remotely and will contribute to the DUNE Near Detector in Batavia, Illinois.
Signatures from agencies in the Czech Republic and Spain have been coordinated and will be finalized in the future.
In the memorandum of understanding for Far Detector 1, the United Kingdom and CERN agreed to contribute to anode plane assemblies; Brazil, the Czech Republic, Italy and Spain will contribute to the photon detection system; CERN will contribute to the high-voltage system; Canada, CERN and the U.K. will contribute to the data acquisition system; and Spain will contribute to the calibration and cryogenics instrumentation.
In the memorandum of understanding for Far Detector 2, CERN and France agreed to contribute to top drift electronics; Brazil, the Czech Republic, France, Italy and Spain will contribute to the photon detection system; France and CERN will contribute to the high-voltage system; Canada, CERN and the U.K. will contribute to the data acquisition system; Spain will contribute to the calibration and cryogenics instrumentation; and CERN and France will contribute to the charge readout planes.
Scientists and engineers from more than 35 countries are partnering with Fermilab to design, build and analyze data from DUNE, which will be installed in the new Long-Baseline Neutrino Facility. Construction of LBNF has begun, and the excavation of the large caverns in Lead, South Dakota for the DUNE Far Detectors is more than 85% complete.
The DUNE collaboration comprises more than 1,400 scientists and engineers from over 200 research institutions. Notably, CERN’s commitment to LBNF and DUNE represents its first investment in infrastructure for a physics experiment outside of Europe. Several countries — France, India, Italy, Poland and the United Kingdom — also are making significant contributions to the Proton Improvement Plan II project, which includes the construction of the 215-meter-long superconducting particle accelerator at Fermilab that will power DUNE.
DUNE will be the world’s most comprehensive experiment to study neutrinos: tiny, lightweight particles that permeate the universe but rarely interact with anything. DUNE will seek to determine whether neutrinos could be the reason the universe is made of matter; look for neutrinos emitted from exploding stars to learn more about the formation of neutron stars and black holes; and watch for a rare subatomic phenomenon that could elucidate the unification of nature’s forces.
To pursue these science goals, DUNE will study neutrino oscillation, a phenomenon in which a neutrino’s property, called flavor, changes as it travels. DUNE will probe this oscillation by shooting a beam of neutrinos 1,300 kilometers straight through the earth, from Fermilab’s accelerator complex in Illinois, through the Near Detector to the Far Detectors located a mile underground at SURF in South Dakota.
The science of DUNE is a global endeavor, and the partnership with funding agencies, scientists and engineers from around the world makes it the first truly international mega science experiment to be hosted on U.S. soil. Additionally, hundreds of students from all corners of the earth will start their careers in science, engineering and computing on this project.
Fermi National Accelerator Laboratory is supported by the Office of Science of the U.S. Department of Energy. The Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
