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 for the CESR-B machine, which has been employed on many light sources in the last several years. 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 develop an advanced design to address the issues of higher luminosity. New developments in the area of HOM absorbers will be adapted and an advanced design for the SRF cryomodule system will be developed.

Commercial Applications and other Benefits as described by the awardee: An advanced SRF system should allow operation of synchrotron light sources with half the number of SRF cavities, providing increased beam lifetime and luminosity and reduced capital costs. A commercial market for these systems already exists.
