Design specification of the single-shot spectrometer. The available Bragg reflections are (111), (220), (333) and (440). The (a) 2θ (detector arm angle), (b) transmission, (c) (pixel energy resolution) and (d) (measurable spectral range) parameters are calculated as functions of photon energy for each available Bragg reflection. In (a), the two dashed lines indicate the available angular range (2θ) defined by the Be window's size. The technical specifications are calculated within the allowed range of 2θ. In (d), is determined by the beam size (FWHM) at the spectrometer's location, which is calculated based on a previous study (Parc et al., 2014). |
