A precise calibration for measurements of electric current has long eluded scientists. Last year, the ampere was redefined based on the charge of a single electron. The next generation of charge-coupled devices, known as skipper CCDs, could provide the sensitivity needed to calibrate the new definition.

Fermilab joins the global celebration of Dark Matter Day. Hear from Fermilab scientists during a special webinar on Saturday, Oct. 31, at 1 p.m. CT. Take a virtual tour of the lab’s dark matter experiments and detectors, and learn how Fermilab is helping answer questions about the mysterious stuff that makes up 25% of our universe.

DOE commended the Fermilab-led LHC CMS Detector Upgrade Project team for completing their project on budget and schedule and for delivering equipment that will enable new discoveries in science for years to come. The award was one of three given this year.

From Inside HPC, Oct. 14, 2020: With the arrival of exascale computing in 2021, researchers expect to have the power to describe the underlying properties of matter and optimize and control the design of new materials and energy technologies at levels that otherwise would have been impossible. Fermilab scientist Andreas Kronfeld talks about how participation in DOE’s Exascale Computing Project can help solve complicated calculations in particle physics.

From Tech Briefs, Oct. 1, 2020: Fermilab has developed a high-power, high-energy, superconducting radio-frequency electron gun for advanced metal additive manufacturing applications. The novel design is based on a technique that eliminates liquid helium entirely and dramatically reduces the complexity of the system.

From NIST, Oct. 13, 2020: Researchers at NIST and their colleagues, including Fermilab scientist Gordan Krnjaic, have proposed a novel method for finding dark matter. The experiment, in which a billion millimeter-sized pendulums would act as dark matter sensors, would be the first to hunt for dark matter solely through its gravitational interaction with visible matter. A three-minute animation illustrates the new technique.

Rubin Observatory will bring new capabilities to the studies of dark matter and dark energy.

Bernstein is overseeing the Fermilab Mu2e experiment as it moves from its construction to installation phase and into a running experiment. A collaboration of nearly 250 scientists at 40 institutions that had to invent technology to get to this point, Mu2e is in an exciting phase, especially for early-career researchers who will not only construct the experiment, but also analyze the data.

From Quanta Magazine, October 2020: This 17-minute podcast episode explores how three physicists stumbled across an unexpected relationship between some of the most ubiquitous objects in math. Hear Fermilab scientist Stephen Parke, DUNE collaborator Deborah Harris of York University, and Fields medalist Terence Tao discuss neutrinos, linear algebra, and the international, Fermilab-hosted Deep Underground Neutrino Experiment.

Visualizing dark matter is not an easy task. Although scientists have reason to believe the mysterious substance makes up about 27% of all the matter and energy in the universe, they still have yet to see it directly; they know it exists only because of its gravitational pull on the visible matter around it. An art exhibit at the Science Gallery Dublin combines art and science to illuminate the invisible nature of dark matter.
