This Snowmass21 Contributed Paper encourages the Particle Physics communityin fostering R&D in Superconducting Nb3Sn coated Copper RF Cavities instead ofcostly bulk Niobium. It describes the pressing need to devote effort in thisdirection, which would deliver higher gradient and higher temperature ofoperation and reduce the overall capital and operational costs of any futurecollider. It is unlikely that an ILC will be built in the next ten years withNb as one of the main cost drivers of SRFs. This paper provides strongarguments on the benefits of using this time for R&D on producing Nb3Sn oninexpensive and thermally efficient metals such as Cu or bronze, while pursuingin parallel the novel U.S. concept of parallel-feed RF accelerator structures.A technology that synergistically uses both of these advanced tools would makean ILC or equivalent machines more affordable and more likely to be built. Sucha successful enterprise would readily apply to other HEP accelerators, forinstance a Muon Collider, and to accelerators beyond HEP. We present and assesscurrent efforts in the U.S. on the novel concept of parallel-feed RFaccelerator structures, and in the U.S. and abroad in producing Nb3Sn films oneither Cu or bronze despite minimal funding.
