Figure 3
Relation between sample incident angle and (a) wavelength selected by the polychromator mirror when used together with the TOF method and (b) the resulting beam divergence for different mirror–sample gaps. Panel (b) is obtained by taking horizontal cuts at fixed wavelength from the shaded wavelength–angle map in panel (a), assuming a wavelength resolution of 5%. The angular width of each cut corresponds to the beam divergence plotted in (b).
