56. Terawatt-Scale Attosecond X-ray Pulses from a Free Electron Laser Cascade

Paris Franz (Stanford University)

Invited talk

High intensity, sub-femtosecond XFEL pulses are key to taking full advantage of nonlinear x-ray spectroscopies and advanced imaging methods. The X-ray Laser-Enhanced Attosecond Pulses (XLEAP) collaboration is an ongoing project for the development of attosecond x-ray modes at the Linac Coherent Light Source (LCLS). Here we report development of a high power attosecond mode via cascaded...

55. Radiation detection and coherent harmonic generation for the PAX Experiment at FACET-II

Rafi Hessami (SLAC National Accelerator Laboratory)

Invited talk

The ongoing Plasma-driven Attosecond X-ray source experiment (PAX) at FACET-II aims to produce coherent soft X-ray pulses of attosecond duration using a Plasma Wakefield Accelerator [1]. These kinds of X-ray pulses can be used to study chemical processes where attosecond-scale electron motion is important. For this first stage of the experiment, PAX plans to demonstrate that <100 nm bunch...

77. Ponderomotive Microbunching for a Superradiant Thomson Source

Brian Schaap (University of Technology Eindhoven)

6/19/23, 5:05 PM

Invited talk

Compact sources offering high-brightness radiation in the extreme ultraviolet to X-ray regime are highly desired. Thomson scattering, in which an electron beam colliding with a laser pulse produces radiation, is a source of X-rays of increasing prevalence in modern labs, complementing large scale facilities like synchrotrons and X-ray free electron lasers. By imposing a density modulation on...

6. First Light at the Israeli THz Superradiant Free Electron Laser

Avraham Gover (Tel Aviv University)

Contributed oral

We report first observation of terahertz super radiant emission from the Israeli Free Electron Laser. This is first demonstration of a THz FEL source based on the scheme of coherent spontaneous superradiant (SR) emission by an ultra-short e-beam bunch. The first measured radiation signal corresponds to a 3.5THz beam output of 180 nanoJ.
The Israeli superradiant FEL operates in the FEL center...

87. An open source platform for integrated design and control of compact radiation sources

David Bruhwiler (RadiaSoft LLC)

Contributed oral

The international collaboration towards a 5th-generation lightsource should adopt an open source platform to enable a) instantaneous collaboration between distributed design teams; b) code benchmarking, multiphysics and code chaining for end-to-end simulation; c) multi-level user support for all relevant codes, from GUI to supercomputer; d) applicability to all subsystems individually,...
