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.
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.
Superconductors conduct large amounts of electricity without losses. They are also used to create very large magnetic fields, for example in MRI machines, to study materials and medicine. Here, researchers developed a fast, new "smart" technique to measure how much current a superconductor can carry using very high pulsed magnetic fields.
Tests of the first Integrated Coil Form test coil wound using REBCO superconducting tape show promise for use in ultra powerful magnets of the future.
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 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.
The compact coil could lead to a new generation of magnets for biomedical research, nuclear fusion reactors and many applications in between.
