Abstract
We are planning a short wavelength FEL experiment combining a micro-wiggler and an X-ray seed pulse. A micro-wiggler makes it possible to lase in the VUV to soft X-ray region using a low-energy electron beam. The development of the micro-wiggler is almost complete. With an intense X-ray seed pulse. quick start-up is expected making the wiggler length short. For the seed X- ray source we will use laser-produced Plasma. The validity of this concert was verified using a simulation code based on the SDE-method. With 10 kW X- ray power for seeding the saturation position is shortened to 5 m.
