  1. 232. Free-Electron Lasing Based on a Laser Wakefield Accelerator (WECI1)

    Novel acceleration and FEL concepts
    Invited Orals

    Laser wakefield accelerators can sustain accelerating gradients more than three orders of magnitude higher than those of radio-frequency accelerators, and are regarded as an attractive option for driving compact X-ray free-electron lasers. However, the realization of such devices remains a challenge owing to the relatively poor quality of electron beams that are based on a laser wakefield...

    Invited Orals

    The breakthrough provided by plasma-based accelerators enabled unprecedented accelerating fields by boosting electron beams to GeV energies within few cm.

    This enables the realization of table-top accelerators able to drive a Free-Electron Laser (FEL), a formidable tool to investigate matter at sub-atomic level by generating X-UV coherent light pulses with fs and sub-fs durations.

    We report the first lasing of a seeded FEL fully driven by a laser plasma accelerator. The experiment was performed at HZDR (Germany), coupling the high quality electron beams of the HZDR laser plasma accelerator with the versatile COXINEL beam manipulation line. Using an external seed at 270 nm, the FEL signal was observed at 275 nm. We explain how this slight red-shift confirms previous...

  4. 10. Bridging the Gap of Storage Ring Light Sources and Linac-Driven Free-Electron Lasers (WECO4)

    Novel acceleration and FEL concepts
    Contributed Oral

    High-gain free-electron lasers (FELs) are driven by short, high-charge density electron beams as only produced at dedicated single pass or recirculating linear accelerators. We describe new conceptual, technical, and modeling solutions to produce subpicosecond, up to ∼100 μJ-energy extreme ultra-violet and soft x-ray FEL pulses at high and tunable repetition rates, from a diffraction-limited...
