The monochromatized or white SR beam from a wiggler magnet installed at the electron storage ring VEPP-3 (2 GeV, 20 kG, 100-200 mA) was used for fluorescence excitation. The working energies ranged from 8 to 35 keY. Without focusing x-ray optics, the spatial resolution was 60/Im with the monochromatic beam and 30,urn with the white SR beam. The minimum detectable concentration of the elements (within the Fe-Sr region) is 10 ppm for 1-3 s exposures per point.

A 100 MeV eight-turn accelerator-recuperator intended to drive a high-power infrared free-electron laser (FEL) is currently under construction in Novosibirsk. The first stage of the machine includes a one-turn accelerator-recuperator that contains a full-scale RF system. It was commissioned successfully in June 2002.
