Since Columbus Superconductors was born by a group of researchers, its solid R&D roots have been influencing the strategy and the development of the company. R&D activities start from the design of the wire, that strongly depends on the application and on the device where it will be implemented. According with customer requirements, R&D team can choose the layout and the materials in terms of:
- final shape (round, square, flat) and cross section
- physical characteristics (magnetic or not magnetic materials, with low or high resistivity, with defined thermal properties)
- superconductive properties (critical currents at operating temperature and magnetic field).
Moreover, the powders could be optimized so as to increase the wire performance on low and high field through the ball milling or the carbon doping.
R&D has to define the better production process to achieve all the specifications veryfing that no degradation occurs on the wire in its final configuration.
