Query: Key directions for research and development of superconducting radio
  frequency cavities   Radio frequency superconductivity is a cornerstone technology for many future
HEP particle accelerators and experiments from colliders to proton drivers for
neutrino facilities to searches for dark matter. While the performance of
superconducting RF (SRF) cavities has improved significantly over the last
decades, and the SRF technology has enabled new applications, the proposed HEP
facilities and experiments pose new challenges. To address these challenges,
the field continues to generate new ideas and there seems to be a vast room for
improvements. In this paper we discuss the key research directions that are
aligned with and address the future HEP needs.
