Duplex magnets use two independent coils powered by capacitor banks to reduce the driven voltages and provide more design flexibility to maximize the generated magnetic fields. The Pulsed Field Facility developed such a duplex magnet to generate magnetic field up to 76.8 Tesla using existing 16-kV, 4-MJ capacitor bank (cap-bank) that now provides important information on a new state of matter in YbB12.
High field superconductor magnets greater than 10 T made from brittle Nb3Sn superconducting wires need special attention to their assembly, strength and endurance. This new study of damage in Nb3Sn superconducting wire from prototype accelerator coils built at CERN provides a path to designing better superconductor cables for the next generation of higher field accelerator magnets.
A recent test coil with more than 1300 meters of conductor successfully demonstrated a new winding technique for insulated REBCO technology and was fatigue cycled to high strain for hundreds of cycles. This is the MagLab's first "two-in-hand" wound coil and the first fatigue cycling test of a coil of this size, both of which are very important milestones on the path to a 40T user magnet.
Grant from the U.S. Department of Energy will further research that will help make the next generation of high-energy particle accelerators.
Tests of high-temperature superconducting REBCO tapes at 4.2 K showed resistance to cyclic loading, demonstrating that it is a promising material for designing HTS magnets of the future.
The world's largest particle collider is getting even larger, and magnet labs are helping lay the foundation.
The successful test of concept shows that the novel design, using a high-temperature superconductor, could help power tomorrow's particle accelerators, fusion machines and research magnets.
Ernesto Bosque is helping to develop a promising superconductor into tomorrow's powerful electromagnets.
In the Netherlands, researchers double down on new discoveries by boosting the power of high-field magnets with lasers.
Two MagLab teams tried marrying vastly different technologies to build a new type of magnet: the Series Connected Hybrid. Decades later, has the oddball pairing panned out?
