Tenacious persistence

Fermilab’s Liz Sexton-Kennedy talks to Symmetry about her lifelong drive to learn and how it led to her current role as chief information officer for Fermilab. Jim Daley spoke to Sexton-Kennedy about her experiences in STEM, her career at Fermilab and a bit about herself.

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.

Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do about an 800-ton magnet originally used to discover new particles? Send it off on a months-long journey via truck, train and ship halfway across the world to detect oscillating particles called neutrinos, of course. It’s all part of the vast recycling network of the physics community.

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 Family Open House is a chance for the whole family to spend an afternoon learning about science in a hands-on way and have fun doing it. This year’s event, running from 1-5 p.m. on Sunday, Feb. 10, will feature the Great Neutrino Hunt, live physics demonstrations, a memorial to Leon Lederman, and several activities for kids and their parents to enjoy.

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.

Facio uses woven textiles to recreate the structure of the cosmos from astrophysical data. A textiles conservator at the Art Institute of Chicago, he sees parallels between an artist’s and a scientist’s work. Facio will be the fifth artist in the residency program, which Fermilab started in 2014.

The Humboldt Foundation invites awardees to undertake prolonged periods of research in collaboration with scientists in Germany and to promote scientific cooperation between research institutions in both Germany and their home country. During his upcoming visit, Eichten intends to continue to study the systematics of systems involving heavy quarks.

Fermilab’s Inclusivity Journal Club seeks answers to difficult social questions in science. A typical meeting includes physicists and postdoctoral researchers as well as non-science staff; students are also welcome to attend. Members read and discuss reports and peer-reviewed papers that address issues such as sexual harassment, implicit bias and best practices for expanding inclusivity.
