Description
We firstly demonstrate, by means of analytical results and PIC simulations,
that 340~attosecond long, 2.3~GeV electron beams with 0.15~$\%$ projected energy spread, 60~nm normalised emittance, and projected 6D-Brightness in excess of $3\times 10^{18}\mathrm{A}/\mathrm{m}^2/0.1\%\mathrm{BW}$ can be generated with a ~200TW~Ti:Sa laser system and a Resonant Multi-Pulse Ionization injection (ReMPI) scheme employing a simplified two-pulses driver. The beam slice analysis reveals its potential for driving a few-spikes X-ray Free-Electron-Laser. Furthermore, the ultra-high projected-quality, and the extreme shortness of the beams make them ideal candidates for the generation of attosecond and quasi-monochromatic $\gamma$ photons through Thomson/Compton-backscattering, or for the injection in subsequent plasma structures to reach TeV energies in staged-LWFA’s.
Preliminary GENESIS simulations results about the related SASE-FEL source configuration, show that a 25~m long undulator can be employed to generate soft X-ray radiation in the water-window, with $>2\times 10^{12} \gamma/$~shot and $1.3\%$~{\it rms} bandwidth.
Finally, we show by preliminary q3D-PIC simulations that KHz repetition rate high-brightness and GeV-scale electron beams can be generated by combing the P-MoPA and ReMPI schemes. ReMPI uses the P-MoPA modulated picosecond pulse to excite a large amplitude plasma wave, and a frequency-doubled portion of the P-MoPA/Ti:Sa ultrashort pulse to extract the electrons from an Argon dopant.
