Modern synchrotron light sources have come to rely upon superconducting radio frequency (SRF) acceleration to achieve high luminosity. To date, the workhorse in this area has been the SRF system developed by Cornell in the mid-1990¿s for the CESR-B machine. However, as the quest for higher performance continues, this system is being stretched beyond its design limits. Required increases in input power, increases in detrimental higher order mode (HOM) power, and new requirements for pressure-vessel-code compliance demand an advanced design for these systems. This project will adapt new developments in HOM absorbers to the development of an advanced SRF cryomodule system that provides higher luminosity. Phase I developed conceptual designs for the cavity and cryomodule by implementing more-structurally-robust helium vessels and providing for a high power coaxial power coupler. In addition, a concept for a next-generation HOM absorber, with broader frequency response and higher power capability, was developed. Phase II will involve the fabrication of the cavity and cryomodule. Commercial Applications and other Benefits as described by the awardee: An advanced SRF system should enable the operation of higher performance synchrotron light sources with fewer SRF cavities, benefiting both in beam lifetime and luminosity, and reducing capital costs
