Future third-generation light sources, such as the NSLS-II synchrotron light source proposed for Brookhaven National Laboratory, push the operating current and subsequent beam power to levels beyond the capabilities of single CESR-B cavities. The proposed light source will require 500mA and 1000kW of radiated beam power that must be provided through the power couplers/windows. This project will develop a power coupler that can provide 500kW to the cavities, reduce the installed RF impedance by a factor of two, and significantly increase the beam lifetime. An innovative cooling mechanism will be provided through the center conductor of a coax type coupler.

Commercial Applications and other Benefits as described by the awardee: The technology would be expected to benefit third and fourth generation light sources, high power FELs, and other high current accelerators that require high power couplers to power SRF cavities.
