Fermilab features

On March 15, Fermilab broke ground on PIP-II, a major new particle accelerator project at Fermilab. Dignitaries from the United States and international partners celebrated the start of the project at the groundbreaking ceremony. The PIP-II accelerator will power the long-term future of the laboratory’s research program, including the international Deep Underground Neutrino Experiment and a suite of on-site experiments.

The U.S. Department of Energy has approved the scope, cost and schedule for the U.S. LHC Accelerator Upgrade Project and has given the first approval for the purchase of materials. This project brings together scientists, engineers and technicians from national laboratories — such as Fermilab, Brookhaven, Berkeley, SLAC and Jefferson labs — to develop two cutting-edge technologies to advance the future of both the Large Hadron Collider and broader collider research.

The MINERvA neutrino experiment has a new crime scene investigation technique, one that takes a hard look at the traces that particles leave before fleeing the scene. Researchers used a new technique in a recent MINERvA neutrino investigation. And the new insights they gained on the workings of nuclear effects can help other neutrino experiments.

Scientists on the ArgoNeuT experiment have developed a method that enables them to better distinguish the tracks that particles leave behind in liquid argon, as well as a way to better differentiate between signals and background. And thanks to the software’s great performance, ArgoNeuT will aid larger neutrino experiments in their quest to understand the nature of the subtle neutrino.

For several weeks, a prototype detector for the Fermilab-hosted Deep Underground Neutrino Experiment collected data using beams from CERN’s particle accelerators. The results show a mature technology exceeding all expectations. It’s the culmination of three years of hard work by a global team dedicated to constructing and bringing the new detector online.

Fermilab’s quantum program includes a number of leading-edge research initiatives that build on the lab’s unique capabilities as the U.S. center for high-energy physics and a leader in quantum physics research. On the tour, researchers discussed quantum technologies for communication, high-energy physics experiments, algorithms and theory, and superconducting qubits hosted in superconducting radio-frequency cavities.

Fermilab scientist Pushpa Bhat was recently elected to the Council of the American Association for the Advancement of Science, the world’s largest scientific society, as a representative for the Section on Physics. Her three-year term begins on Feb. 18. The AAAS Council establishes general policies for the association and reviews all of its programs.

For the first time, scientists have demonstrated that low-energy neutrinos can be thoroughly identified with a liquid-argon particle detector. The results, obtained with the ArgoNeuT experiment, are promising for experiments that use liquid argon to catch neutrinos, including the upcoming Deep Underground Neutrino Experiment.

Fermilab has finalized an agreement with construction firm Kiewit-Alberici Joint Venture to start pre-excavation work for the Long-Baseline Neutrino Facility, which will house the enormous particle detectors for the Deep Underground Neutrino Experiment. The South Dakota portion of the facility will be built a mile beneath the surface at the Sanford Underground Research Facility in Lead, South Dakota.

In a new series of exhibits in the Fermilab Art Gallery, the Fermilab Archives will feature influential works loaned by the private collection of a Fermilab scientist. It kicks off with the current exhibit, which features works from the 17th and 18th centuries. Each display, which will rotate approximately once a month, will consist of several volumes illustrating a common theme in the evolution of physics.
