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.
Fermilab is America’s particle physics and accelerator laboratory. Our vision is to solve the mysteries of matter, energy, space and time for the benefit of all.
Accelerator magnets — how do they work? Depending on the number of poles a magnet has, it bends, shapes or shores up the stability of particle beams as they shoot at velocities close to the speed of light. Experts design magnets so they can wield the beam in just the right way to yield the physics they’re after. Here’s your primer on particle accelerator magnets.
Fermilab, Brookhaven National Laboratory and Lawrence Berkeley National Laboratory have achieved a milestone in magnet technology. Earlier this year, their new magnet reached the highest field strength ever recorded for an accelerator focusing magnet. It will also be the first niobium-tin quadrupole magnet to operate in a particle accelerator — in this case, the future High-Luminosity Large Hadron Collider at CERN.
Fermilab technology developed for particle accelerators offers a valuable opportunity to search for a hypothesized particle that would resemble a particle of light. These dark photons could help us understand the large part of our universe that we know is there but have yet to observe.
Fermilab, UNICAMP and São Paulo Research Foundation collaborate on major international projects for neutrino research
Under a new agreement, the University of Campinas and the São Paulo Research Foundation will play important roles in the Long-Baseline Neutrino Facility and the international Deep Underground Neutrino Experiment, hosted by Fermilab.
The groundbreaking ANNIE experiment at Fermilab has seen its first neutrino events. This milestone heralds the start of an ambitious program in neutrino physics and detector technology development. It is also a cause for celebration by the international ANNIE collaboration, composed of groups from Germany, the United Kingdom and the United States.
Fermilab in the news
From Physics World, March 24, 2020: Scientists using the first year of data from the Dark Energy Survey, which is led by Fermilab, establish that there is a correlation between the positions of gravitational lenses — deduced from the stretching of distant galaxies — and gamma-ray photons. A data comparison from gravitational lensing and gamma-ray observations reveals that regions of the sky with greater concentrations of matter emit more gamma rays.
From CERN Courier, March 23, 2020: A quadrupole magnet for the High-Luminosity LHC has been tested successfully in the U.S., attaining a conductor peak field of 11.4 tesla — a record for a focusing magnet ready for installation in an accelerator. The device is based on the superconductor niobium-tin and is one of several quadrupoles being built by U.S. labs and CERN for the HL-LHC, where they will squeeze the proton beams more tightly within the ATLAS and CMS experiments to produce a higher luminosity.
From The Chicago Maroon, March 22, 2020: The University of Chicago, working with scientists from Argonne National Laboratory, has developed a new fiber-optic quantum loop to expand quantum communication experiments. Along with the UChicago quantum loop, Argonne is working with Fermilab to plan and develop a similar two-way quantum link network.
