Figure 13
The measured Kα emission line of Ne8+, showing a FWHM of 0.29 eV giving a resolving power of ∼3200. This width is larger than expected from the simulations shown in Fig. 11 where a resolving power of ∼11100 is shown. This emission line is expected to have very small intrinsic broadening, and we attribute the observed broadening as being due to e.g. a source size larger than the XFEL beam FWHM, or a misalignment of the optical components in the spectrometer.
