Pump-probe X-ray holographic imaging of laser-induced cavitation bubbles with femtosecond FEL pulses

Nature Communications, 2021
Cavitation bubbles show many nonlinear characteristics of liquid and gas phase. Here the authors demonstrate coherent diffractive imaging of cavitation bubble using infrared pump and XFEL probe and discuss the formation and evolution of the bubbles.

Nanometer-resolution hard X-ray near-field ptychography with multilayer Laue lenses [PDF]

EPJ Web of Conferences
In coherent X-ray diffraction imaging, resolution is limited by the scattering power of the sample, where high-angle signals are weak and compete with background and noise.

The FERMI free-electron lasers [PDF]

Journal of Synchrotron Radiation, 2015
FERMI is a seeded free-electron laser (FEL) facility located at the Elettra laboratory in Trieste, Italy, and is now in user operation with its first FEL line, FEL-1, covering the wavelength range between 100 and 20 nm. The second FEL line, FEL-2, a high-gain harmonic generation double-stage cascade covering the wavelength range 20–4 nm, has also ...

Simple convergent-nozzle aerosol injector for single-particle diffractive imaging with X-ray free-electron lasers

Structural Dynamics, 2015
A major challenge in high-resolution x-ray free-electron laser-based coherent diffractive imaging is the development of aerosol injectors that can efficiently deliver particles to the peak intensity of the focused X-ray beam. Here, we consider the use of

Microsecond hydrodynamic interactions in dense colloidal dispersions probed at the European XFEL

IUCrJ, 2021
Many soft-matter systems are composed of macromolecules or nanoparticles suspended in water. The characteristic times at intrinsic length scales of a few nanometres fall therefore in the microsecond and sub-microsecond time regimes.

Ultrafast light-induced dynamics in the microsolvated biomolecular indole chromophore with water

Nature Communications, 2022
Experimentally following the ultrafast dynamics of microsolvated molecules is challenging due to the inherently produced soup mix of various gas-phase aggregates.

Minimizing attosecond CEP jitter by carrier envelope phase tuning [PDF]

EPJ Web of Conferences, 2019
Minimizing the CEP jitter of isolated attosecond pulses (IAP) will be important for future applications. This jitter is experimentally and theoretically investigated and can be minimized when the driving pulse is near its Fourier limit but with slightly ...

Optical guiding in a free electron laser [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1985
Abstract The coherent interaction between an optical wave and an electron beam in a free electron laser (FEL) is shown to be capable of optically guiding the light. The effect is analyzed using a two-dimensional approximation for the FEL equations, and using the properties of optical fibers.

An Optimized Approach for Serial Crystallography Using Chips

Crystals, 2023
Serial crystallography is a rapidly developing method for the determination of the structure of biomolecules at room temperature at near-atomic resolution from an ensemble of small crystals. Numerous advances in detectors, data analysis pipelines, sample
