An ensemble of soprano, strings, piano and electronics gives voice to the mysterious neutrino in David Ibbett’s latest musical work as Fermilab guest composer. Mapping the waves of neutrino oscillation onto melodies played by the strings, Ibbett sonifies a neutrino phenomenon typically represented in abstract mathematical expressions. Hear the performance and Ibbett’s comments in this four-minute video.

Missing March Madness? Let Fermilab fill a small part of the void created in these times of social distancing and shelter-in-place. Participate in Fermilab’s sendup of the NCAA tournament: March Magnets. Learn about eight different types of magnets used in particle physics, each with an example from a project or experiment in which Fermilab is a player. Then head over to the Fermilab Twitter feed on March 30 to participate in our March Magnets playoffs.

It was 1969, and Keith Coiley was a high-schooler who heard about a good-paying summer job working at what was then named the National Accelerator Laboratory. That year, Johnny Green, also in high school, was recruited to join the lab, as was Curtis Danner a year later. Fifty years later, they continue as productive members of the Fermilab workforce and community. In recognition of Black History Month, they talk about their experiences as black men working at an international science center over a half-century.

The USCMS collaboration has received approval from the Department of Energy to move forward with final planning for upgrades to the giant CMS particle detector at the Large Hadron Collider. The upgrades will enable it to take clearer, more precise images of particle events emerging from the upcoming High-Luminosity LHC, whose collision rate will get a 10-fold boost compared to the collider’s design value when it comes online in 2027.

After 32 years at Fermilab, the individual who has served as the lab’s extraordinary photographer — and so much more — is leaving. Reidar Hahn’s legacy will live on in his photos, the many services he’s provided for the lab, and the countless, selfless ways he has helped the lab community.

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.

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.
