Abstract
Superconducting radio frequency (SRF) cavities are used to accelerate electron beams worldwide. Brookhaven National Laboratory (BNL) has proposed to build the NSLS­II, a third generation light source, and has identified SRF cavities as the technology of choice. The final machine configuration will require four single-­cell 500 MHz SRF cavities fed by four 300 kW klystrons to compensate beam loss. In addition, two passive two-­cell 1.5 GHz Landau (3rd harmonic) SRF cavities are required to lengthen the bunch, thereby increasing beam lifetime to greater than 3 hours. This project will develop a 1500 MHz SRF Landau cavity. Whereas previously designed cavities used niobium sputtered onto high­ purity copper, this cavity will utilize bulk niobium to enable the stringent specifications and requirements for the NSLS­II ring to be satisfied. Phase I demonstrated technical feasibility by completing the preliminary cavity and cryomodule design. Phase II will finalize the cryomodule design and prototype critical aspects of the system: SRF cavities, power coupler, HOM spectrum, and frequency tuners. Commercial Applications and other Benefits as described by the awardee: The development and demonstration of this new type of superconducting radio frequency Landau cavity should open up many new applications for both scientific and industrial accelerators
