During a routine test, two HL-LHC magnets unexpectedly flatlined. Was it just a coincidence, or did they have a common foe?

From Wonderful Engineering, January 10, 2022: A video trip of the 17-ton superconducting magnet ring designed to be the focal point of Fermilab’s Muon g-2 subatomic particle experiment that was moved from Brookhaven, New York to Batavia, Illinois.

From New Atlas, December 1, 2021: Neutrino research and other experiments may have new magnets to use in the future. Physicists at Fermilab have developed a superconducting magnet that can perform at high temperatures and higher field strength. Read more about the work of Vladimir Shiltsev and Alexander Zlobin.

Large, powerful magnets are a vital component of particle accelerators. The general rule is, the stronger the magnetic field, the better. For many particle accelerator applications, it is as important how fast a magnet can reach its peak strength and then ramp down again. A team at Fermilab now has achieved the world’s fastest ramping rates for accelerator magnets using high-temperature superconductors.

A super-precise experiment at Fermilab is carefully analyzing every detail of the muon’s magnetic moment. The Fermilab Muon g-2 collaboration has announced it will present its first result at 10 a.m. CDT on April 7.

From Berkeley Lab, Feb. 17, 2021: Fermilab is part of a team of national labs that designed, built and fully tested a prototype magnet for today’s and tomorrow’s light sources. These light sources let scientists see things once thought impossible. They can use these visions to create more durable materials, build more efficient batteries and computers, and learn more about the natural world.

The U.S. Department of Energy has given the U.S. High-Luminosity Large Hadron Collider Accelerator Upgrade Project approval to move full-speed-ahead in building and delivering components for the HL-LHC, specifically, cutting-edge magnets and accelerator cavities that will enable more rapid-fire collisions at the collider. The collider upgrades will allow physicists to study particles such as the Higgs boson in greater detail and reveal rare new physics phenomena. The U.S. collaborators on the project may now move into production mode.

Later this decade, the Large Hadron Collider will be upgraded to the High-Luminosity LHC. What does “luminosity” mean in particle physics, and why measure it instead of collisions?

After more than 15 years of work, scientists at three DOE national laboratories have succeeded in creating and testing an advanced, more powerful superconducting magnet made of a niobium-tin compound for use in the next generation of light sources.

From CERN Courier, Jan. 13, 2021: The US LHC Accelerator Upgrade Project, led by Fermilab scientist Giorgio Apollinari, is now entering the production phase in the construction of magnets for the upcoming High-Luminosity LHC, an upgrade of the current Large Hadron Collider. U.S. labs are building magnets that will focus beams near the ATLAS and CMS particle detectors.
