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.

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.

Future particle colliders will need strong magnets to steer high-energy particle beams as they travel close to the speed of light on their circular path. A group at Fermilab has achieved a record field strength of 14.1 teslas for a particle accelerator steering magnet, breaking the 11-year record.

The Johannes Gutenberg University Mainz, Germany, has taken a significant step to participate in the international Deep Underground Neutrino Experiment, hosted by Fermilab. Fermilab and the university have signed an agreement to jointly appoint an internationally renowned researcher who will strengthen the experimental particle physics research program at JGU Mainz and advance a German contribution to DUNE. This is the first Fermilab joint agreement with a university in Germany.

Ketevan Akhobadze moved to Fermilab from the country of Georgia and found a new home. She now creates exhibits as a tool to introduce the public to the exciting science done at Fermilab.

Engineers at Fermilab have shown that sometimes, to reshape the metal heart of a particle accelerator, what you need is a balloon. The new, patented technique is a novel solution to a problem that affects an essential component of accelerators: superconducting cavities.

The funding supports initiatives in the rapidly evolving field of quantum computing. Fermilab scientists and engineers are simulating advanced quantum devices that will in turn improve particle physics simulations. They’re also developing novel electronics to work with large arrays of ultracold qubits.

For years, U.S. institutions have been working to upgrade the hardware in the behemoth CMS particle detector at the Large Hadron Collider, enabling it to profit fully from the LHC’s increasing collision energy and intensity. With CD-4 approval, the Department of Energy formally recognized that the USCMS collaboration, managed by Fermilab, met every stated goal of the upgrade program — on time and under budget.

The first major superconducting section of the PIP-II accelerator has come to Fermilab: the first of 23 cryomodules for the future accelerator. The cryomodules’ job is to get the lab’s powerful proton beam up and moving, sending it to higher and higher energies, approaching the speed of light. This first cryomodule also represents a successful joint effort between Argonne National Laboratory and Fermilab to design and produce a critical accelerator component for the future heart of Fermilab.
