The continuum of the conventional x-ray tube despite of its comparatively low intensity provides the possibility to record high resolution fluorescence and absorption spectra in the ultrasoft x-ray region. A system is described which uses a concave grating grazing incidence spectrometer with automatic photoelectric recording in conjunction with a high power rotating anode allowing high currents (up to 4 A) at relatively low voltages (4 to 10 kV). The device permits recording emission and absorption spectra of oxygen, nitrogen, carbon, and other elements at resolutions comparable with the inherent widths of the inner levels involved in the transitions.
