Superconducting Radio Frequency Cavities Coating Techniques | |
|
||
| Thin film superconducting coatings offer a valuable alternative to conventional bulk niobium cavities mainly by reducing the cost of raw material and enhancing the heat exchange efficiency thanks to the copper substrate. The current and future superconducting radiofrequency (SRF) cavities designs and working frequencies lead to a variety of shapes and sizes to be coated. In this work we present the constraints to coat complex 3D geometries and the challenges of obtaining uniform SC layer properties with different coating techniques. It will be supported by concrete examples from ongoing cavities coating production and studies for future projects at CERN. Finally the R&D methodology, from plasma simulation to layer characterization, will be described. | ||
