Review of cryomodules and SRF challenges for light source energy recovery linacs.
Superconducting rf (SRF) is the technology of choice for future energy-recovery linac (ERL)-based light source facilities. ERL-based light sources are required to run in a continuous wave (cw) mode as compared to the International Linear Collider (ILC), which requires a moderate repetition rate. The difference in the two operating modes (low duty factor and cw) will necessitate a fresh look at the SRF parameter space specifically suited for light source ERLs. There are still open questions regarding the choice of rf frequencies, cryomodule design, cavity cell design and number of cells, Q factor, accelerating gradient, and higher-order-mode damping. In addition, the cryoplant for such facilities will need to be designed to handle on the order of tens of kW of cooling at 2 K. The existing cryoplants cannot provide a level of efficiency to make it cost effective to operate such facilities. Therefore, consolidated R&D efforts are needed to find a more robust solution to improve the overall refrigeration efficiency.
