Fig. 3: Reconstruction of a synthetic density of states from a RIXS spectrum at varying levels of noise, using a realistic SASE XFEL profile.
From: Resonant inelastic x-ray scattering in warm-dense Fe compounds beyond the SASE FEL resolution limit
A total of 50 single shots were used. We show examples of the synthetic RIXS spectra in a–c, with the corresponding reconstructions in d–f. The technique is robust to noise, owning to the strong inductive bias given by the model, and the stochastic nature of the SASE pulse profile Φ that allows us to oversample the DOS. The zero of the DOS energies is centred at the resonance.
