The Fermilab magnet team has done it again. After setting a world record for an accelerator magnet in 2019, they have broken it a year later.

In a June 2020 test, a demonstrator magnet designed and built by the magnet team at the Department of Energy’s Fermilab achieved a 14.5-tesla field strength for an accelerator steering dipole magnet, surpassing their previous record of 14.1 T.

This test is an important step toward addressing the demanding magnet requirements of a future hadron collider under discussion in the particle physics community. If built, such a collider would be four times larger and almost eight times more powerful than the 17-mile-circumference Large Hadron Collider at the European laboratory CERN, which operates at a steering field of 7.8 T. Current future-collider designs estimate the field strength for a steering magnet — the magnet responsible for bending particle beams around a curve — to be up to 16 T.

“Our next goal is to break the ’15-tesla wall’ and advance the maximum field in accelerator steering magnets to 17 T and even above, significantly improve magnet quench performance and optimize cost,” said Fermilab scientist Alexander Zlobin, who leads the magnet project. “Reaching these goals will provide strong foundation for future high-energy colliders.”

    Intersting.

    Guess what happens and what you would have invented if and when particles can be controlled like this and you can do it on a Industrial scale for larger objects than just particles?
