| Abstract Scope |
The promise of fusion technology stemming from high magnetic fields produced by coated conductors and recent records in all-superconducting magnets reinforce the need to study critical currents (Jc) in magnetic fields above 30T. Achieving Jc measurements in pulsed magnetic fields provides a tool for this. Using Fast Programmable Gate Array electronics we measured reproducible current–voltage curves (I-V) in different superconductor thin films and single crystals. We show it is possible to measure Jc in high pinning coated conductors up to 65T. We compare measurements in two of the magnet systems available at Los Alamos Pulsed Field Facility of the National High Magnetic Field Laboratory and show that we are now able to measure Jc continuously as a function of field (H) in our newly commissioned mid-pulse magnet. We determined the window of dH/dt where meaningful data can be obtained (where t is the time). |
