      keV Compton X-ray source driven by SC linac at KAERI

A quasi-monochromatic X-rays source based on the KAERI SC linac system has been de- signed 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 per- centage of energy spread and 10^7 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.

An upgrade of SC linac at KAERI to ERL

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 isochro- nous to avoid any problems with longitudinal beam instability. The total relative emit- tance degradation through the whole machine is 1.5. The FEL will be based on a 2 m heli- cal 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.

      N.Skrinsky (Budker Institute of Nuclear Physics, Novosibirsk, Russia) Design of an Experiment on Plasma Wakefield Acceleration at Budker INP

The project of an experimental facility based upon the VEPP-5 injection complex at Bud- ker INP is described. Due to a good quality of electron beam and special beam preparation system based on arc bunch compressor the facility opens several possibilities for studies of the plasma wakefield acceleration: high peak beam currents, arbitrary beam profiles, and long term beam-plasma interaction (up to the full driver depletion). End-to-end simu- lations of the beam dynamics are presented. Due to nonlinear effects in the bunch com- pressor the peak beam current is limited to 3 . Coherent synchrotron radiation in mag- nets appears to be an important issue for maximum compression ratios resulting in many-

fold increase of the initial beam emittance
