FLASH, the FEL user facility at DESY (Hamburg, Germany), is operated with an electron beam energy up to 1 GeV corresponding to a photon wavelength down to 6.5 nm. FLASH consists of an electron source to generate a high quality electron beam, a superconducting linac of six TESLA type accelerating modules, and an undulator section to produce laser like coherent FEL radiation. About half of the beam time is scheduled for the FEL users, and the rest is for accelerator and FEL physics studies. Experience gathered at FLASH is important not only for further improvements of the FLASH facility itself, but also for the European XFEL and for the ILC R&D effort.
