A quasi-monochromatic X-rays source based on the KAERI SC linac system has been designed and is being manufactured now. 10 MeV 10 mA electron beam together with 20 W 1.06 um laser beam will be used for 1.8 keV Compton X-ray generation with a few percentage of energy spread and 107 photons per second. A simple straight beamline was designed to deliver the electron beam with no degradation of its emittance and energy spread and to focus it to a proper size to produce the desired X-rays. We expect the first demonstration of 1.8 keV Compton X-ray generation in autumn, 2006.

A project of an ERL at Korea Atomic Energy Research Institute is described. The future ERL will be connected to the existing machine without any modification. It consists of two 180 deg. bents and two straight sections: one for an FEL, another for a Compton X-ray source. One can choose the source controlling the magnets. The total ERL is isochronous to avoid any problems with longitudinal beam instability. The total relative emittance degradation through the whole machine is 1.5. The FEL will be based on a 2 m helical in-vacuum undulator made of permanent magnets. One mirror of the optical cavity is blind and made of copper, the other one, the outcoupler, is semi-transparent and made of CVD diamond. The expected average FEL power is a few kW, the tuning range 35, ,70 um.
