“…This amounts to 1,760 pulses per second-already almost 15 times more pulses per unit time than the next highest repetition rate, hard X-ray FEL. A high-intensity MHz optical laser system has been commissioned recently and is now available at the SPB/SFX instrument of the EuXFEL [24]. Our experiments require the synchronization of each optical laser pulse with a corresponding X-ray pulse, in the end at MHz rates, and each time with picosecond precision.…”

The European XFEL (EuXFEL) is a 3.4-km long X-ray source, which produces femtosecond, ultrabrilliant and spatially coherent X-ray pulses at megahertz (MHz) repetition rates. This X-ray source has been designed to enable the observation of ultrafast processes with near-atomic spatial resolution. Time-resolved crystallographic investigations on biological macromolecules belong to an important class of experiments that explore fundamental and functional structural displacements in these molecules. Due to the unusual MHz X-ray pulse structure at the EuXFEL, these experiments are challenging. Here, we demonstrate how a biological reaction can be followed on ultrafast timescales at the EuXFEL. We investigate the picosecond time range in the photocycle of photoactive yellow protein (PYP) with

“…Pump-probe laser. In addition to the HIBEF optical lasers, the pump-probe (PP) laser, developed at European XFEL (Palmer et al, 2019), offers intense laser pulses tailored to the unique time structure of the XFEL bunch pattern. This laser, which operates with the non-collinear optical parametric amplifier (NOPA) scheme, has a central wavelength of 800 nm with a close to Fourier-limited bandwidth for pulses down to 15 fs duration.…”

The European XFEL delivers up to 27000 intense (>1012 photons) pulses per second, of ultrashort (≤50 fs) and transversely coherent X-ray radiation, at a maximum repetition rate of 4.5 MHz. Its unique X-ray beam parameters enable groundbreaking experiments in matter at extreme conditions at the High Energy Density (HED) scientific instrument. The performance of the HED instrument during its first two years of operation, its scientific remit, as well as ongoing installations towards full operation are presented. Scientific goals of HED include the investigation of extreme states of matter created by intense laser pulses, diamond anvil cells, or pulsed magnets, and ultrafast X-ray methods that allow their diagnosis using self-amplified spontaneous emission between 5 and 25 keV, coupled with X-ray monochromators and optional seeded beam operation. The HED instrument provides two target chambers, X-ray spectrometers for emission and scattering, X-ray detectors, and a timing tool to correct for residual timing jitter between laser and X-ray pulses.

“…Chemical reactions in solution phase are triggered by femtosecond laser radiation provided by a specially developed burst-mode femtosecond laser system, the Pump-Probe Laser (PPL) [39]. The system consists of an amplified slab laser producing 800 fs long pulses with 1030 nm wavelength and a non-collinear optical parametric amplifier (NOPA) to generate broadband laser pulses centered at 800 nm, which are routinely compressed down to 15 fs pulse duration.…”

Ultrafast X-ray Photochemistry at European XFEL: Capabilities of the Femtosecond X-ray Experiments (FXE) Instrument

Time-resolved X-ray methods are widely used for monitoring transient intermediates over the course of photochemical reactions. Ultrafast X-ray absorption and emission spectroscopies as well as elastic X-ray scattering deliver detailed electronic and structural information on chemical dynamics in the solution phase. In this work, we describe the opportunities at the Femtosecond X-ray Experiments (FXE) instrument of European XFEL. Guided by the idea of combining spectroscopic and scattering techniques in one experiment, the FXE instrument has completed the initial commissioning phase for most of its components and performed first successful experiments within the baseline capabilities. This is demonstrated by its currently 115 fs (FWHM) temporal resolution to acquire ultrafast X-ray emission spectra by simultaneously recording iron Kα and Kβ lines, next to wide angle X-ray scattering patterns on a photoexcited aqueous solution of [Fe(bpy)3]2+, a transition metal model compound.
