Production process: industrial quality assurance, output, and speed
In view of expanding commercial markets, HTS production at Bruker EST is based on physical deposition processes. The production technology affords uniform quality characterized by high critical currents and favorable mechanical properties of the conductor material as well as cost efficiency at high yields and throughput rates: Polished stainless steel substrate tape is cleaned before the YSZ buffer is applied by alternating beam assisted deposition (ABAD). Subsequently the CeO2 buffer and the superconducting polycrystalline YBCO layer are added by high-resolution pulsed laser deposition (HR-PLD). Applying the gold or silver film by physical vapor deposition (PVD) finalizes the layer architecture on the substrate which is then annealed and galvanic copper-plated. Dependable for commercial application
