Abstract
Future third generation light sources, such as the NSLS-II synchrotron light source proposed for Brookhaven National Laboratory (BNL), push the operating current and subsequent beam power to levels beyond the capabilities of single CESR-B/KEKB cavities. The proposed light source requires 500mA and 1000kW of radiated beam power that must be provided through the power couplers/windows. The development of a power coupler that can provide greater than 500kW to the cavities would reduce the installed RF impedance by a factor of two and significantly increase the beam lifetime. This project will develop a fundamental power coupler that can transmit greater than 500kW of power, with innovative cooling through the center conductor of a coax type coupler. A separate effort proposes to develop the cavity for this source; thus, if both grants are awarded, the power coupler will be integrated with the cavity. Phase I identified a general coupler configuration and layout with a KEKB-like cavity. An analysis showed that the RF requirements were met. Phase II will develop the final design of the coupler, with input from BNL. Commercial Applications and other Benefits as described by the awardee: The power coupler should find application in third and fourth generation light sources, high power Free Electron Lasers, and other high current accelerators requiring high power couplers to power SRF cavities.
