TI - Exponential Growth of Radiation in an EUV FEL Driven by an Electron Beam Generated in a Plasma Wakefield Accelerator J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - Exponential gain of extreme ultraviolet radiation at 27 nm was observed in a free-electron laser (FEL) driven by the electron beam generated in a laser-driven plasma wake-field accelerator at SIOM (China, Shanghai). This experiment, showing that the quality of the beam generated in the laser plasma accelerator is sufficient to sustain amplification in a FEL, represents a long awaited fundamental milestone. In addition, more recently a first demonstration of FEL exponential gain was also achieved in a beam-driven plasma accelerator at a wavelength of 830 nm at INFN (Frascati, Italy). The performances of these FELs cannot match those available in existing FEL facilities. However, these experiments represent a technological breakthrough and pave the way for FELs driven by extremely compact accelerators. PB - JACoW Publishing CP - Geneva, Switzerland ER -
