One of the jobs of the HTS team is to test samples of high temperature superconductor (HTS) tape to determine how they perform in a magnetic field. Here, HTS Magnet Physicist Matt Bristow shows us the tests he runs to determine the critical current and tells us why it's important to know this information. He also demonstrates why HTS is a superior choice over copper when it comes to making powerful magnets for fusion devices.
