Statistical properties of the radiation from SASE FEL operating in a post-saturation regime with and without undulator tapering

, 2015
We describe statistical and coherence properties of the radiation from x-ray free electron lasers (XFEL) operating in the post-saturation regime. We consider practical case of the SASE3 FEL at the European XFEL.

Data reduction activities at European XFEL: early results

Frontiers in Physics
The European XFEL is a megahertz repetition-rate facility producing extremely bright and coherent pulses of a few tens of femtoseconds duration. The amount of data generated in the context of user experiments can exceed hundreds of gigabits per second ...

Towards an Optimal Sample Delivery Method for Serial Crystallography at XFEL

Crystals, 2020
The advent of the X-ray free electron laser (XFEL) in the last decade created the discipline of serial crystallography but also the challenge of how crystal samples are delivered to X-ray.

Review of technical achievements in PAL-XFEL

AAPPS Bulletin, 2022
The X-ray Free Electron Laser of Pohang Accelerator Laboratory (PAL-XFEL) was opened for the user in 2017. PAL-XFEL was the third XFEL facility in the world and well known for the small timing jitter of FEL radiation. This success was possible because of

Experimental Demonstration of Attoseconds-at-Harmonics at the SASE3 Undulator of the European XFEL

Photonics, 2023
We report on observations of single spike spectra (3–13% of events) upon employing a previously proposed method for single spike generation via harmonic conversion. The method was tested at the soft X-ray SASE3 undulator of the European XFEL.

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Machine-learning-enhanced automatic spectral characterization of x-ray pulses from a free-electron laser

Communications Physics
A reliable characterization of x-ray pulses is critical to optimally exploit advanced photon sources, such as free-electron lasers. In this paper, we present a method based on machine learning, the virtual spectrometer, that improves the resolution of ...
