Abstract:
This Report proposes a comprehensive approach focused on the expertise and collaborative network that has been built in Europe and in the entire world over the past years. The IFAST WP9 team has developed a program aligned with the priorities deemed essential by the TF SRF community for continuous progress in this field. Ten priority topics have been identified on TF developments: 1 - Niobium on copper, 2 - Nb3Sn on Cu and Nb, 3 - Other superconductors (other A15, MgB2, Other) on Cu and Nb, 4 - Multilayers (SIS structures), 5 - Surface functionalization), but also on key activities that enable these developments, 6 - Cu cavity production and surface preparation, 7 - General Characterization / Surface science, 8 - Deposited cavities preparation and RF testing, 9 - Theory, 10 - Industrialization). This Report is structured into 4 parts: (1) Introduction, where the challenges of the SRF technology are described (2) Detailed Topics, where the context and challenges are described in detail for each of the 10 topics THIN-FILM SRF ROADMAP REPORT Deliverable: D9.1 Date: 07/01/2025 Grant Agreement 101004730 PUBLIC 2 / 47 (3) Main recommendations. For each topic: - A R&D program is detailed by priority order - A global budget and manpower are recommended - Additional targeted programs and investments are proposed 4) General conclusion By addressing the challenges outlined in this document and fostering a collaborative research environment, the global community can benefit the full potential of this technology for applications from high-energy collisions and high-intensity hadron/neutron sources to light sources, cavity detectors, quantum computing or emerging fields like compact accelerators poised to revolutionize industrial processes and medical diagnostics.
