The Spectrum Analyzer is used to measure the wavelength spectrum from single shots of the x-ray beam. This is achieved by diffracting a small portion of beam intensity through a grating. The diffracted beam from the grating passes through a curved single crystal. The curvature of the crystal will generate a dispersive beam distributing the wavelength band over an angular interval. The distributed radiation is collected by a Gotthard detector to an adjustable 2-theta scattering angle.
