“…Many works have tried to overcome this by applying multivariate statistical analyses as to separate the information given in the energy region of interest (ROI) in different parts, corresponding to the different spectral lines present. 5,6 Nevertheless, it would be useful to have a spectrometer capable of resolving the L emission lines successfully. Reviewing the emission lines of these elements, an energy resolution of around 10 eV is enough to allow for the desired discrimination.…”

In this work, the design, fabrication, and evaluation of a compact, one-shot spectrometer based on a segmented conically bent crystal analyzer are described. The system is a "one-shot" wavelength dispersive spectrometer, which has a crystal analyzer with an innovative geometry. It reaches an energy resolution of around 8 eV for Mn Kα 1 line, which is at least an order of magnitude better than the commonly used energy dispersive spectrometers for fluorescence, and is comparable to current wavelength dispersive spectrometers. The prototype spectrometer fabricated in this work avoids angle scans that most wavelength dispersive spectrometers require, has the advantage of a sample-detector distance of only 146 mm, and allows for the simultaneous measurement of approximately a 2 keV window. This system is suitable to be used at synchrotron radiation facilities and free electron lasers, and it can even be adapted to an x-ray tube in any conventional x-ray laboratory.
