Opportunities and Challenges of the Hard X-ray Self-seeding System at the European XFEL | |
|
||
| The Hard X-ray Self-seeding system (HXRSS) at the European XFEL provides users with longitudinally coherent X-ray FEL pulses with narrow bandwidth and high spectral density. With this setup we have achieved a maximum spectral density of about 1 mJ/eV at 9 keV. Combined with the MHz repetition rate, it opens up exciting new opportunities in a wide range of scientific fields. However, the increasing user demand and expectations also poses challenges in machine tuning and operation parameter ranges. We will summarize the HXRSS performance we have achieved and the user delivery experiences in the last two years. | ||

Application of Superconducting Undulator Technology for Hard X-ray Production at European XFEL | |
|
||
| The advancement of superconducting undulator (SCU) technology is of strategic importance for the future development of the European XFEL facility. To build the know-how to implement superconducting undulators for its future upgrades, several projects are ongoing: a prototype SCU module (S-PRESSO) for an afterburner in the hard X-ray undulator line SASE2 is being procured; two test stands (SUNDAE1 and SUNDAE2) for the characterization of SCU are being developed; advanced SCU coils are designed and manufactured in house. In this presentation, we describe the status and plans of those projects and highlight their expected performances. | ||

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. | ||
