Objective 1: Advanced SRF materials growth: Developing improved growth methods and understanding the impact of realistic (non-ideal) surfaces on performance.
Deliverable: New and improved growth methods and alternative materials for increased cavity efficiency and operating temperature (to be completed by Fall 2026).
Objective 2: Multi-layers and inhomogeneous layers: Increasing RF performance via surfaces by design.
Deliverable: Optimized inhomogeneous surface layers for increased cavity efficiency and increased accelerating fields (to be completed by Fall 2026).
Objective 3: Higher efficiency and higher fields: Demonstrate higher RF performance in proof-of-principle SRF cavities and study RF superconductivity under extreme conditions.
Deliverable: Surfaces from non-Niobium at 20 MV/m corresponding to a 10´ reduction in cooling power (to be completed by Fall 2024).
Deliverable: Surfaces capable of sustaining higher accelerating field with ultra-high efficiencies, and surfaces approaching 400 mT (to be completed by Fall 2026).
