Short Introduction to Opera for Superconducting Devices

With modern high-temperature superconductor (HTS) materials, and the improved tolerance they exhibit not only toward temperature but field changes, comes renewed endeavour in developing systems that capitalize on their novel properties. This improved tolerance opens up the use of superconducting materials in AC or transient magnetic systems such as transformers, generators and fault current limiters, in addition to DC systems (e.g. MRI/NMR and particle accelerator magnets) that are already well established
