EuXFEL operation at very hard X-rays: single-shot upstream XGM detectors for SASE1 and SASE2 were HAMP (Xe gas target), whereas SASE3 was operated with XGMD (Kr gas target). The electron bunches were accelerated to 16.4 GeV. The SASE1, SASE2 and SASE3 photon energies were 24 keV, 30 keV and 1.6 keV, respectively. Left: graphs are the arithmetical averages over the single-shot pulse energies. Right: actual single-shot pulse energies plotted as bars. The average light powers at all SASE sources are shown. |
