Unlike third-generation SR facilities, next-generation light sources will need extensive R&D to be conducted to define the final optimum configuration. A comprehensive R&D program is needed to address the challenges of implementing a high-repetition-rate seeded-FEL facility, while also advancing capabilities and technologies for other facility concepts such as ERLs (energy recovery linacs) with common needs. By developing advanced technologies of high-repetition-rate (of order MHz), low-emittance electron injectors; CW superconducting-RF linacs; and optical manipulations, the next generation of FEL facility will be able to open up new areas of research, complementing the FEL facilities currently being built or planned, as well as enhancing the technology base for other accelerator-based light sources

Efficient radiation at wavelengths down to 1-nm, with an electron beam energy of approximately 2 GeV, requires a bright electron beam with low-emittance, low energy spread, and high peak current. This, together with the requirement of high-repetition rate, drives our current R&D program.
