Development of a CW Superconducting RF Booster Cryomodule for Future Light Sources

Advances in superconducting linear accelerators, especially superconducting radio frequency (SRF) accelerators, during the past 10 years have opened up new opportunities, such as the International Linear Collider, Rare Isotope Accelerator, spallation neutron sources, free electron lasers and advanced light sources. Future light sources likely will use CW SRF linacs (linear accelerators) with requirements that are unique to their need. In collaboration with Lawrence Berkeley National Laboratory (LBNL), this project will develop a CW SRF booster cryomodule for future light source injectors. Phase I will develop the design and identify requirements for the accelerating structure and cryomodule, based on systems efficiency, beam dynamics simulations, emittance compensation, and higher order mode (HOM) analysis. Phase II will finalize the cryomodule design and prototype critical aspects of the system, such as the SRF cavities, power coupler, HOM spectrum, and frequency tuners. Commercial Applications and other Benefits as described by the awardee: The principal markets for CW SRF booster cryomodules are the U.S Government and International research laboratories.
