From Gizmodo, Sept. 13, 2019: Physicists at Fermilab have produced and tested a powerful magnet of the sort that could appear in the next generation of particle colliders. Fermilab scientist Alexander Zlobin talks with Gizmodo about the lab’s recent milestone achievement in reaching 14.1 teslas for a steering magnet.

From Tia Sáng, Sept. 13, 2019: Để xây dựng thế hệ máy gia tốc proton mới có khả năng gia tốc hạt lớn hơn, các nhà khoa học cần những nam châm mạnh nhất để có thể lái các hạt tới gần tốc độ ánh sáng lưu chuyển quanh một vòng tròn. Với một kích cỡ vòng tròn cho trước, để đưa năng lượng của chùm tia đạt mức cao hơn, các nam châm của máy gia tốc cần đạt được lực mạnh hơn để giữ cho chùm tia đi đúng hành trình của mình.

From, Sept. 13, 2019: Naukowcy z Fermilab poinformowali o wygenerowaniu najsilniejszego pola magnetycznego stworzonego na potrzeby akceleratorów cząstek. Nowy rekord wynosi 14,1 tesli, a wynik taki uzyskano w magnecie schłodzonym do 4,5 kelwinów, czyli -268,65 stopnia Celsjusza. Poprzedni rekord, 13,8 tesli, został osiągnięty przed 11 laty w Lawrence Berkeley National Laboratory.

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.

Superconducting magnets are the workhorses that steer particle beams in most particle accelerators. The problem is that these magnets require costly cryogens to cool. Now, researchers have found a way to create high-temperature superconducting magnets. A group at Fermilab proposed a novel magnet design that works at much higher temperatures. It could substantially simplify magnet fabrication and cooling.

On March 6, a 30,000-pound B3 magnet was changed out in the F17 area. The old magnet had failed, and the magnet mover was used to remove it and install the new magnet.

From IEEE Spectrum, Jan. 30, 2019: If realized, the Future Circular Collider will produce magnetic fields nearly twice as strong as the LHC and accelerate particles to unprecedented energies of 100 teraelectron volts, compared to the Large Hadron Collider’s energies of 13 TeV. Whereas the magnetic system at the LHC can achieve strengths of 8.3 teslas, the FCC system would be able to achieve 16 T.
