The first hard x-ray beamline at BESSY II has been installed at a superconducting 7 T wavelength shifter. The main optical elements of the beamline are a double-multilayer monochromator (DMM) and a double-crystal monochromator (DCM). Depending on the application, the two devices are used separately or in-line. The main applications of the monochromatic radiation with photon energies up to 60 keV are x-ray fluorescence analysis, micro computed tomography, x-ray topography, detector calibration and reflectometry. Depending on the requirements, the used beam size varies between 1.5µm and 10mm.

The BAMline is specialized for nondestructive material characterization using different methods. The main applications of the monochromatic radiation with photon energies up to 60 keV are x-ray fluorescence analysis at BAMline Spectroscopy, micro computed tomography, x-ray topography, detector calibration and reflectometry at BAMline Imaging. Calculable undispersed radiation up to 200 keV is available for radiometric applications. Depending on the requirements the used beam size varies between 1.5 and 10000µm.
