Surface preparation of SRF cavities Sample Clauses

Surface preparation of SRF cavities. Surface preparation requires state-of-the-art clean room techniques, challenging etching procedures (electro-polishing and buffered chemical polishing, both using hydrofluoric acid), and sophisticated surface modification methods like Nitrogen doping or infusion. In some cases, successfully applied techniques are actually not stable enough to finish R&D efforts. Surface preparation of SRF cavities is clearly cutting-edge technology. Within AMICI, several institutes operate technology platforms required for successful R&D. All present and future projects rely on respective infrastructure. Some few laboratories have larger scale facilities in operation, which is clearly to the benefit of other projects. Recently started large-scale projects use these existing platforms. Further R&D is widely needed for future projects. Collaboration exists and needs to be sustained. Actually studied surface preparation techniques need to become more stable. There is still high development potential. In parallel, knowledge transfer to industry is essential since large-scale production of structures including surface preparation can only be done at vendors. Projects need structures delivered ready for cold RF testing. Only a stable and successful surface preparation allows the construction and later operation of large facilities. Unstable surface preparation leads to a repetitive preparation and cold RF testing which then become a real cost driver.
