Two-Fold Reduction of Jc Anisotropy in FeSe0.5Te0.5 Films Using Low-Energy Proton Irradiation
Abstract
High in-field performance and low anisotropy of critical current density Jc are important for superconducting wires/tapes in rotating machine and magnet applications. Here, we report measurements of angular dependence of critical current density Jc in pro-ton irradiated FeSe0.5Te0.5 (FST) films at magnetic field up to 35 T. Here, we observed two-fold reduction in the Jc anisotropy of FST films at 4.2 K and 15 Tesla magnetic field by irradiation with low-energy (190 keV) proton. In light of recent demonstration of roll-to-roll irradiation process successfully incorporated in the standard 2G HTS long length production wire, low-energy proton irradiation can be a practical solution to enhance the performance of iron-based super-conducting wires and tapes, as low-energy ion sources are inexpensive to operate and are readily available commercially.
