Spectrometer for Hard X-Ray Free Electron Laser Based on Diffraction Focusing

V. G. Kohn, O. Y. Gorobtsov, I. A. Vartanyants

X-ray free electron lasers (XFELs) generate sequences of ultra-short, spatially coherent pulses of x-ray radiation. We propose the diffraction focusing spectrometer (DFS), which is…
