Abstract: Intense attosecond pulse trains generated by the seeded FEL FERMI have been temporally characterized using a covariance-based approach with single-shot photoelectron spectra [1,2]. Due to the high intensities achieved by FEL pulses, such attosecond pulse trains are ideal candidates for investigating nonlinear processes and, eventually, controlling them by varying the phase of...

Understanding photoinduced structural and electronic dynamics in chemical and biological systems requires experimental tools with femtosecond time resolution and sensitivity at the atomic scale. In this context, we describe the Alvra instrument at the Swiss X-ray free-electron laser (SwissFEL), which was developed to address these challenges by combining time-resolved X-ray spectroscopy and...

Self-assembly of gold nanoclusters produces nano- to mesoscale structures with enhanced optical and electronic properties, making them promising building blocks for functional nanomaterials and plasmonic devices. These properties are commonly investigated using spectroscopic techniques, which typically provide only indirect information about the underlying structure. Directly characterizing...

Traditionally, neutron scattering has been the main technique to study spin order and excitations, such antiferromagnetism of LiErF4 [1]. However, exceptional improvements in terms of brilliance of accelerator-based X-ray sources have elevated X-ray scattering as an effective complementary technique that enables elemental sensitivity via electronic resonance effects, as well as the ability to...

Oxygen vacancies are not merely defects in materials but play a crucial role in determining their mechanical, optical, electrical, and catalytic properties.[1] Understanding and controlling these vacancies is essential for the development of advanced energy conversion and storage technologies.[2] SrCoO₂.₅ exhibits a brownmillerite structure with alternating layers of metal–oxygen octahedra and...

We have developed an all-electronic setup for synchronizing X-ray free-electron laser (XFEL) pulses in phase with microwave pulses at carrier frequencies up to 40 GHz, achieving sub-picosecond timing jitter. We demonstrate the capabilities of this synchronization scheme performing X-ray-detected ferromagnetic resonance experiments at an XFEL. In this experiment, conducted at the Maloja...

Over the past decade, intense femtosecond X-ray pulses generated by XFELs have greatly advanced structure determination of radiation-sensitive samples through the “diffraction-before-destruction” approach. The ultrashort duration of XFEL pulses allows diffraction data to be collected before significant structural changes occur, thereby enabling determination of atomic structures beyond the...

Attosecond science with ultrafast optical pulses has revolutionized our understanding of electron dynamics, enabling direct observation of charge migration, electron correlation effects, and field-driven phenomena on their intrinsic timescales. Recent advances in electron accelerator technologies at XFEL facilities have extended attosecond techniques into the hard X-ray regime [1,2], allowing...

The pulse-length preserving double grating monochromator beamline FL23 at the XUV/soft x-ray free-electron laser FLASH went into user operation beginning of 2024. The beamline is designed to work in the soft X-ray regime covering the spectral range between 60-950 eV with a spectral resolving power of approximately 2000 [1]. A flexible microfocus at the experimental station is provided by a...
