(Color online) A three-dimensioanl (3D) view of the three channel crystal spectrometer. The input window consists of a diaphragm with three slits, one for each crystal, a pinhole, thin sheets of beryllium to shield visible light, and lead shielding for hard x rays and other background radiation.
Optical scheme of the crystal spectrometer.
(Color online) Wavelength positions on film calculated for first (red) through fifth (yellow) reflection orders of mica.
(Color online) Spectrometer dispersion, calculated numerically, in first through sixth orders of reflection (from right to left) for spherically bent mica.
(Color online) Comparison of numerical calculation of for this spectrometer (green points) with the approximation of Swartz et al. (pink). Also shown is the numerical calculation of (violet).
(Color online) calculated numerically with for first (red) through fifth (yellow) reflection orders of mica.
Cu -shell spectra obtained experimentally. The brightest lines have been identified and are labeled above.
