| Research Abstract |
REBa2Cu3Oy (REBCO) superconductors are aimed for use in several applications such as cables and magnet applications. The most of the in-field studies have been made using the Maximum Lorentz Force (MLF) configuration, but in applications this is not always the case. Therefore it is important to study other configurations where current (J) and field (H) are parallel to each other (i.e. Lorentz Force Free (LFF)). If increasing critical current (Jc) in LFF could be achieved, large current capacity DC cables could be designed. In this work, we investigate the effect of artificial pinning centers (APC) on the Jc in FF configurations. We systematically controlled size and density of APC in REBCO wire. We found that APC plays important role in the improvement of Jc in LFF.
