MS&T Science Highlights
Pulsed magnets are designed to operate near their structural limits to be able to generate extremely high magnetic fields. The coils have a limited life expectancy and thus need to be replaced on occasion. Fabrication of these large coils are now being done at the MagLab where advanced nondestructive examinations can be performed. Because of more rigorous quality controls and improvements in high-strength conductors and reinforcement materials, the lifetime of these coils can be extended.
MagLab scientists and engineers have developed a special coating on Bi-2212 superconducting wire for electrical insulation in superconducting magnets that will enable the wire to be used in ultra-high field nuclear magnetic resonance magnets.
Bi-2223 shows promise for 30-tesla all-superconducting instrument for nuclear magnetic resonance.
New technique transforms common materials into powerful magnets.
Producing a high magnetic field that is also very stable and uniform, the unique Series Connected Hybrid magnet is being put to work on NMR experiments never before possible.
Scientists explore using one magnet to disrupt the field of another.
A first-of-its-kind magnet called for a first-of-its-kind approach to quench analysis. MagLab engineers delivered.
Using a novel method of winding the magnet coil that dispensed with the traditional insulation, the MagLab reached another world record and laid the foundation for more to come.
Tapping into MagLab expertise on superconductors and cryogenics, a research team built a novel neutron scattering device that is more efficient and produces better data than previous techniques.
New calculations that reveal the workings of a new type of high-field research magnet will aid in future magnet designs.
Reduced-size prototype coils for the 32 T all-superconducting magnet have been successfully tested. The results include the generation of 27 T, which is a record for superconducting magnets.
The Series Connected Hybrid magnet that is under fabrication at the NHMFL will utilize current leads containing high temperature superconductor to deliver 20 kA with low heat loads to the helium circuit. The leads have been successfully tested and are ready for installation into the magnet system.
The seven-year collaboration with the Helmholtz Zentrum Berlin resulted in a 26 T magnet for neutron scattering. This magnet is very similar to the FSU/NSF series-connected hybrid magnet and suggests that the FSU magnet will also be successful, thereby enabling new science on two continents with two very different sets of experimental techniques.
Mn-Ga has been characterized as a candidate lower-cost material for substituting rare earth materials in permanent magnets.
The MagLab has delivered the resistive insert coils for the 25-Tesla Series Connected Hybrid Magnet for the Helmholtz-Zentrum Berlin. This magnet system includes a unique conical warm bore with 30 degree opening angle and will be used for neutron-scattering experiments and an unprecedented 25T central field. This constitutes a 47% increase in magnetic field available for these experiments while also providing an increase in solid-angle.
The MagLab has successfully completed construction of the cold-mass of a series-connected hybrid magnet for the Helmholtz-Zentrum Berlin.
A prototype high-temperature superconducting coil for the 32 T all-superconducting magnet was constructed with YBCO tape and successfully tested in the large-bore resistive magnet at the MagLab.
MagLab engineers are building two cable-in-conduit superconducting coils for hybrid magnets, each with a resistive inner coil and a superconducting outer coil.
