Production and Characterization of Hard X-rays Beyond 25 keV | |
|
||
| Dedicated R&D programs, aimed for delivering ultra-hard X-rays beyond 25 keV for advanced user experiments, have been launched at the European XFEL. Characterization of the electron beam and the photon beam transport to the instrumentation have been carried out. Given the very first experiments, optimized SASE intensities of 0.8 mJ at 24.58 keV and 0.3 mJ at 30.24 keV, both lasing at the fundamentals, have been simultaneously demonstrated at two hard X-ray beamlines of the facility. These experiments were carried out using optimized low-emittance electron beams based on existing undulators with a 4 cm period and 16.4 GeV electron beam energy. It has also been shown, that the transport of 30 keV photon beams to the user experiments was made possible. The obtained results will be presented. Further discussions on the realization of ultra-hard X-rays using advanced techniques, as well as improved longitudinal beam diagnostics of the facility will be given in detail. | ||

Generation of Intense Attosecond Pulses at the European XFEL | |
|
||
| X-ray free-electron lasers (XFELs) have paved the way for significant advancements in attosecond science by generating intense, ultrashort pulses. We are currently developing AttoSecond Pulses with eSASE and Chirp-Taper schemes (ASPECT) project at the European XFEL, designed to exploit these capabilities. In its initial stages, ASPECT will be used to produce attosecond-long pulses at two out of the three SASE lines at the European XFEL: SASE1 and SASE3, dedicated to producing hard and soft x-rays respectively. In this presentation, we will report design studies and preliminary experimental results at the European XFEL. | ||
