High-resolution Russian-German beamline at BESSY

The superior performance of the high-resolution Russian-German bending-magnet beamline at BESSY is demonstrated by measuring photon flux and photoionization spectra in the spectral region of the 2,-1(3) resonance of doubly-excited He as well as at the 1s absorption thresholds of gas-phase N-2, O-2, and Ne. It is shown that even after 6 years of successful operation, the beamline remains to provide a solid basis for a further development of the Russian-German scientific cooperation in the field of applications of synchrotron radiation.
