Laboratory for the detailed examination of large series of niobium sheets for the production of superconducting cavities
The production of state-of-the-art superconducting accelerator cavities requires high quality niobium material. Therefore DESY developed and is using a special eddy current scanning device to search for inclusions in the Niobium sheet material. A total of almost 15,000 sheets delivered from different vendors were scanned for the European XFEL project. Also all sheets needed for the production of LCLS-II cavities were scanned at DESY. In-kind contributors to the ESS project profit as well from the existing infrastructure.
