Abstract
We present a cylindrically curved GaAs x-ray spectrometer with energy resolution \Delta E/E = 1.1\cdot 10^{-4}and wave-number resolution of \Delta k/k = 3\cdot 10^{-3} allowing plasmon scattering at the resolution limits of the Linac Coherent Light Source (LCLS) x-ray free-electron laser. It spans scattering wavenumbers of 3.6 to 5.2/AA\ in 100 separate bins, with only 0.34\% wavenumber blurring. The dispersion of 0.418~eV/13.5\,\mu...
