Studying the microstructure of Glidcop® AL-60 conductor
The MagLab's ultrahigh-field pulsed magnets require materials with both high mechanical strength and high electrical conductivity. One of these materials is Glidcop® AL-60, an alumina particle strengthened copper. This research studies the microstructure of this material to improve the construction and endurance of these magnets.
Testing REBCO Critical Current Using a Superconducting Transformer
A new device enables the testing of superconducting cables to high current without the high helium consumption associated with traditional current leads. This superconducting transformer will play an important role in testing cables needed for next-generation superconducting magnets.
Special High-Strength Conductor Testing Improves Future Pulsed Magnet Lifespan
Three non-destructive testing methods are developed for inspection of high strength, high conductivity wires which are used to wind ultra-high field pulsed magnets at the National MagLab. We expect the lifetime of future magnets to exceed those of past magnets due to these improvements in quality control.
"Test Coil Zero" on the Path to 40T
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.

In-House Fabrication of Outsert Coil 1 for the 100T Pulsed Magnet
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.
