Update on laser-driven X-ray sources at ELI Beamlines

International Conference on X-Ray Lasers 2020, 2021
Three main paths have been selected within the ELI Beamlines research program for transforming driving laser pulses into brilliant beams of short wavelength radiation: High-order harmonic generation in gases, Plasma X-ray sources, and sources based on ...

Gaming the beamlines—employing reinforcement learning to maximize scientific outcomes at large-scale user facilities

Machine Learning: Science and Technology, 2021
Beamline experiments at central facilities are increasingly demanding of remote, high-throughput, and adaptive operation conditions. To accommodate such needs, new approaches must be developed that enable on-the-fly decision making for data intensive ...

Dosimetry of Thermal Neutron Beamlines at a Pulsed Spallation Source for Application to the Irradiation of Microelectronics

IEEE Transactions on Nuclear Science, 2021
Gas electron multiplier (GEM) detectors and activation foils have been used for dosimetry of thermal beamlines of a pulsed neutron source. The first is an active detector that performs measurements using the time-of-flight technique, taking advantage of ...

Generation of intense magnetic wakes by relativistic laser pulses in plasma

Scientific Reports, 2023
The emergence of petawatt lasers focused to relativistic intensities enables all-optical laboratory generation of intense magnetic fields in plasmas, which are of great interest due to their ubiquity in astrophysical phenomena.

A hierarchical approach for modeling X-ray beamlines: application to a coherent beamline [PDF]

Journal of Synchrotron Radiation, 2019
Different approaches to simulate a modern X-ray beamline are considered. Several methodologies with increasing complexity are applied to discuss the relevant parameters that quantify the beamline performance. Parameters such as flux, dimensions and intensity distribution of the focused beam, and coherence properties are obtained from simple analytical ...

Data Acquisition System Based on the Bluesky Suite in the Shanghai Synchrotron Radiation Facility

Applied Sciences, 2023
The Shanghai Synchrotron Radiation Facility Phase-II Project is now under construction and it consists of 16 newly built advanced beamlines. The experiments carried out at these new beamlines tend to be characterized by high flux, multi-mode, ultra-fast ...

Coherent combining of broadband pulses after free space optical parametric amplification [PDF]

EPJ Web of Conferences
In this study, we present the proof of concept of the polarization-based filled-aperture coherent combination of two distinct broadband sub-20fs transform limited pulse duration optical parametric chirped pulse amplification systems in free-space.

The Generic Beamline Concept of the PETRA III Undulator Beamlines [PDF]

AIP Conference Proceedings, 2007
The conversion of the PETRA storage ring at DESY to a third generation synchrotron radiation light source poses a challenge to the design of the beam transport system. The total power in the white beam will be as high as 7.5kW in the case of the 5m long undulator at 100mA. The power density will be 476 W/mm2 at 20m from the source.

Phase-matched high-order harmonic generation in pre-ionized noble gases

Scientific Reports, 2022
One of the main difficulties of efficiently generating high-order harmonics in long neutral-gas targets is to reach the phase-matching conditions. The issue is that the medium cannot be sufficiently ionized by the driving laser due to plasma defocusing ...
