abstract = {The European X-ray Free-Electron Laser Facility in Germany
delivers x-ray pulses with femtosecond pulse duration at a
repetition rate of up to 4.5 MHz. The free-electron laser
radiation is created by the self-amplified spontaneous
emission (SASE) process, whose stochastic nature gives rise
to shot-to-shot fluctuations in most beam properties,
including spectrum, pulse energy, spatial profile,
wavefront, and temporal profile. Each spectrum consisting of
many spikes varies in width and amplitude that appear
differently within the envelope of the SASE spectrum. In
order to measure and study the SASE spectrum, the HIgh
REsolution hard X-ray single-shot (HIREX) spectrometer was
installed in the photon tunnel of the SASE1 undulator
beamline. It is based on diamond gratings, bent crystals as
a dispersive element, and a MHz-repetition-rate strip
detector. It covers a photon energy range of 3 keV–25 keV
and a bandwidth of $0.5\%$ of the SASE beam. The SASE spikes
are resolved with 0.15 eV separation using the Si 440
reflection, providing a resolving power of 60 000 at a
photon energy of 9.3 keV. The measured SASE bandwidth is 25
eV. In this paper, we discuss the design specifications,
installation, and commissioning of the HIREX spectrometer.
The spectral results using Si (110), Si (111), and C (110)
crystals are presented.},
