Roadmap: • Main Goal: Chart a ten-year research roadmap for RF acceleration technology that improves performance and reduces cost for a future accelerators for HEP. • Features: – Development a set of performance targets and metrics for SRF components (sources, couplers, tuners, etc. ) – Short, medium and long term goals and milestones for • Component development. • Improving the understanding of the fundamental processes contributing to RF performance. • Material property improvement. – Synergies between SRF And RF technology; and other national and international efforts – If needed, the development of intermediate facilities or projects to demonstrate viability of technology. 3 1/27/2017 V.

Strategy for SRF Components and RF source development “Strategy is a high level program to achieve one or more goals under conditions of uncertainty. Strategy typically involves two major processes: formulation and implementation. • Formulation involves analyzing the environment or situation, making a diagnosis, and developing guiding policies. • Implementation refers to the action plans taken to achieve the goals established by the guiding policy. ” Wikipedia 4 1/27/2017 V.
