Figure 4
From: Single-shot X-ray absorption spectroscopy at X-ray free electron lasers
Left panels—XFEL spectra of the ‘best mode’ coupled with a controlled photon energy drift to enlarge the average spectral range. The two spectra from the incident and transmitted spectrometers are represented in gray and black respectively. Middle panels—Single-shots (blue line) and 10 shots averaged absorption spectra (orange line). Right panel—Large spectral range absorption spectra obtained for 1 to 64 accumulated shots compared with a long time accumulation spectra from ESRF (light green).
