From Bulgarisches Wirtschaftsblatt, Nov. 11, 2020: Während die Wissenschaftler im Fermi National Accelerator Laboratory des US-Energieministeriums auf die mit Spannung erwarteten ersten Ergebnisse des Muon g-2-Experiments warten, setzen die mitarbeitenden Wissenschaftler des Argonne National Laboratory des DOE weiterhin das einzigartige System ein, das das Magnetfeld im Experiment mit beispielloser Präzision abbildet.

In a collaborative project with Fermilab, Argonne scientists mapped the magnetic field inside a vacuum with unprecedented accuracy. Results will be used in an experiment to shed light on the Standard Model of particle physics.

Fermilab scientists have broken their own world record for an accelerator magnet. In June, their demonstrator steering dipole magnet achieved a 14.5-tesla field, surpassing the field strength of their 14.1-tesla magnet, which set a record in 2019. This magnet test shows that scientists and engineers can address the demanding requirements for a future particle collider under discussion in the particle physics community.

From Lawrence Berkeley National Laboratory, June 17, 2020: While COVID-19 risks had led to a temporary halt in fabrication work on high-power superconducting magnets built by a collaboration of three national labs for an upgrade of the world’s largest particle collider at CERN in Europe, researchers at Berkeley Lab are still carrying out some project tasks. Fermilab scientist Giorgio Apollinari, head of the U.S.-based magnet effort for the HL-LHC, is quoted in this piece.

From Semiconductor Engineering, April 6, 2020: Fermilab, Brookhaven National Laboratory and Lawrence Berkeley National Laboratory have built an enormous superconducting magnet — one of 16 — that will be used in the High-Luminosity Large Hadron Collider particle accelerator project at CERN in Europe.

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.

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.

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.

From Cold Facts, Sept. 17, 2019: Scientists at Fermilabhave achieved the highest magnetic field strength ever recorded for an accelerator steering magnet, setting a world record of 14.1 teslas, with the magnet cooled to 4.5 kelvin or minus 450 degrees Fahrenheit. Lawrence Berkeley National Laboratory held the previous record of 13.8 teslas, achieved at the same temperature, for 11 years.
