Compact ring FEL as a source of high-power infrared radiation

Summary:Ring FELs [N.A. Vinokurov, O.A. Shevchenko, Nucl. Instr. And Meth. A 528 (2004) 491] were proposed mainly to improve the quality of radiation of X-ray FELs. Their main advantage is the absence of mirrors. It appears that this advantage is also useful for high-power FELs. Another reason to build infrared ring FEL is the proof of principle for shorter wavelength FELs. Therefore, we considered the scheme of infrared ring FEL which requires ERL with beam energy 50 MeV. Using extensive simulations we developed requirements for electron beam parameters and magnetic system of ring FEL. In spite of rather compact design such FEL may provide more than 10 kW average power.
