Press Release

Fermilab's 500-mile neutrino experiment up and running

With construction completed, the NOvA experiment has begun its probe into the mysteries of ghostly particles that may hold the key to understanding the universe. Image: Fermilab/Sandbox Studio

Editor's note: Visit the press release Web page to view three videos — including a new animation and a new time-lapse video — related to the NOvA experiment.

It's the most powerful accelerator-based neutrino experiment ever built in the United States and the longest-distance one in the world. It's called NOvA, and after nearly five years of construction, scientists are now using the two massive detectors — placed 500 miles apart — to study one of nature's most elusive subatomic particles.

Scientists believe that a better understanding of neutrinos, one of the most abundant and difficult-to-study particles, may lead to a clearer picture of the origins of matter and the inner workings of the universe. Using the world's most powerful beam of neutrinos, generated at the U.S. Department of Energy's Fermi National Accelerator Laboratory near Chicago, the NOvA experiment can precisely record the telltale traces of those rare instances when one of these ghostly particles interacts with matter.

Construction on NOvA's two massive neutrino detectors began in 2009. In September, the Department of Energy officially proclaimed construction of the experiment completed, on schedule and under budget.

"Congratulations to the NOvA collaboration for successfully completing the construction phase of this important and exciting experiment," said James Siegrist, DOE associate director of science for high energy physics. "With every neutrino interaction recorded, we learn more about these particles and their role in shaping our universe."

NOvA's particle detectors were both constructed in the path of the neutrino beam sent from Fermilab in Batavia, Illinois, to northern Minnesota. The 300-ton near detector, installed underground at the laboratory, observes the neutrinos as they embark on their near-light-speed journey through the Earth, with no tunnel needed. The 14,000-ton far detector — constructed in Ash River, Minnesota, near the Canadian border — spots those neutrinos after their 500-mile trip and allows scientists to analyze how they change over that long distance.

For the next six years, Fermilab will send tens of thousands of billions of neutrinos every second in a beam aimed at both detectors, and scientists expect to catch only a few each day in the far detector, so rarely do neutrinos interact with matter.

From this data, scientists hope to learn more about how and why neutrinos change between one type and another. The three types, called flavors, are the muon, electron and tau neutrino. Over longer distances, neutrinos can flip between these flavors. NOvA is specifically designed to study muon neutrinos changing into electron neutrinos. Unraveling this mystery may help scientists understand why the universe is composed of matter and why that matter was not annihilated by antimatter after the big bang.

Monster neutrino solves cosmic-ray mystery

From New Scientist, Oct. 1, 2014

A cosmic coincidence could be the first clue to the origin of a high-energy neutrino spotted in Antarctica — and may help pinpoint the source of high-energy cosmic rays that bombard Earth's atmosphere.

Cosmic rays are massive charged particles that barrel through deep space with energies that dwarf those achieved at particle accelerators on Earth. Some may be accelerated to such high speeds by supernovas, but others have mysterious roots.

The Nobel Prize in physics goes to three men who gave us blue light-emitting diodes, used daily in your smartphone screen

From The Washington Post, Oct. 7, 2014

This year's Nobel Prize in physics goes to researchers whose findings you probably rely on just about every day (or, if you're like me, just about every minute). The blue light-emitting diodes they helped create are taking over lightbulbs as we know them, but already see universal use in smartphone flashlights and displays.

At an announcement in Stockholm on Tuesday, the Nobel Prize committee awarded this year's prize in physics to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura. The three men — Akasaki from Meijo University, Amano from Nagoya University (both in Nagoya, Japan) and Nakamura from UC Santa Barbara — produced blue light beams from their semi-conductors in the early 1990s. Until then, we could create red and green light, but blue remained elusive.

Neutrinos are us

Joe Lykken

Last month marked the successful completion of the NOvA project. The NOvA experiment is our biggest step yet toward realizing our ambition of Fermilab leading the world in neutrino science with particle accelerators. NOvA will be the most powerful probe so far of a key question: Which is the heaviest of the three known neutrinos? The resolution of this mass hierarchy puzzle will be crucial to understanding all of the other mysteries of neutrinos.

Tomorrow's labwide celebration reminds me that in the past few months we've had lots of other good news about ν's. At the beginning of the summer, a Physical Review Letter from the MINERνA collaboration presented the first high-statistics direct measurements of nuclear effects in neutrino scattering using different targets in the same neutrino beam. A couple of weeks later the MicroBooNE detector was successfully moved to its experimental hall and is now being commissioned for first data taking early next year.

In July the Fermilab Physics Advisory Committee recommended that the lab provide R&D resources towards LAr1-ND, a new liquid-argon neutrino detector supported by the National Science Foundation in addition to DOE. This follows the recent commitments from both CERN and Italy's INFN to help refurbish ICARUS, the world's largest liquid-argon detector, and transfer it to Fermilab. These developments were a big boost to the Short-Baseline Neutrino (SBN) task force, consisting of representatives from the LAr1ND, MicroBooNE and ICARUS collaborations and coordinated by Fermilab's Peter Wilson. The SBN task force is working to realize the P5 recommendation to develop a short-baseline neutrino program, in collaboration with international partners, that synergizes with the P5 vision of LBNF, a new international long-baseline neutrino program hosted at Fermilab.

Fermilab's neutrino future looks even brighter this week with the launch of our Neutrino Division, headed by Gina Rameika. The new division will operate the current program, including NOvA, MicroBooNE, MINERνA, MINOS+ and LArIAT, while helping to coordinate and execute the future international program of short- and long-baseline experiments. The Neutrino Division will provide support to the worldwide community to participate in all aspects of Fermilab-hosted neutrino science.

And did I mention the newly completed west remote operations center in Wilson Hall? You'll have a chance to visit ROC West, the operations hub for our neutrino program, at tomorrow's celebration.

Daya Bay places new limit on sterile neutrinos

The experiment that produced the latest big discovery about ghostly particles called neutrinos is trying its hand at solving a second neutrino mystery.

The Daya Bay Reactor Neutrino Experiment reported in Physical Review Letters [on Oct. 1] that it has narrowed the region in which the most elusive kind of neutrino, the sterile neutrino, might exist.

Located in southern China, the experiment studies low-energy neutrinos and their antimatter counterparts streaming from the nearby Daya Bay and Ling Ao nuclear power plants.
