Fermilab and the University of Bern in Switzerland have signed an agreement to develop detector components for the laboratory’s neutrino experiments. The agreement is the first of its kind between Fermilab and a Swiss university.

Latin America has reached a pivotal moment in experimental particle physics and astrophysics research. Throughout the month of October, Symmetry will highlight important places, explain significant milestones, and introduce you to some of the people who have shaped and are continuing to shape particle physics and astrophysics in Latin America.

A collaboration led by Fermilab and Stanford University combines their expertise in quantum science and accelerator technologies to build the world’s largest atom interferometer. The instrument will push the boundaries of quantum physics into macroscopic scales, providing a gateway for dark matter searches and tests of gravitational waves.

For the first time, a team at Fermilab has cooled and operated a superconducting radio-frequency cavity — a crucial component of superconducting particle accelerators — using cryogenic refrigerators, breaking the tradition of cooling cavities by immersing them in a bath of liquid helium. The demonstration is a major breakthrough in the effort to develop lean, compact accelerators for medicine, the environment and industry.

Solving equations in neutrino physics, a trio of theorists doing research at Fermilab discovered a mathematical identity that had eluded mathematicians for centuries. Working with Field Medal winner Terence Tao, they now have derived formal proofs of the new identity.

Today’s quantum computing processors must operate at temperature close to absolute zero, and that goes for their electronics, too. Fermilab’s cryoelectronics experts recently hosted a first-of-its-kind workshop where leaders in quantum technologies took on the challenges of designing computer processors and sensors that work at ultracold temperatures.

Scientists working on the MINERvA experiment at Fermilab have examined a few ways neutrons can affect the measurements of antineutrino interactions.

The Dark Energy Survey has delivered dark energy constraints combining information from four of its primary cosmological probes for the first time, an approach that may help design other experiments into cosmic acceleration.

Join us on Wednesday, Sept. 25, at 6 p.m. at the Pritzker Auditorium in Chicago for a special event celebrating the life and legacy of Leon Lederman and looking forward to the future of particle physics. Presented by the Chicago Council on Science and Technology and Fermilab, in conjunction with the the Chicago Public Library, the program will include presentations, a question-and-answer panel with physicists and a miniature physics slam featuring students from IMSA.

Working on hardware doesn’t come easily to all physicists, but Francesca Ricci-Tam has learned that what matters most is a willingness to put in the practice.
