  • beat wave experiments at Ecole Polytechnique
    AIP Conference Proceedings (American Institute of Physics); (United States), 2008
    Co-Authors: F Amiranoff, J.-r. Marquès, Francois Jacquet, A Dyson, M Laberge, F Moulin, E Fabre, P Benkheiri, J Meyer, P. Miné
    Abstract:

    We summarize the results obtained in the context of the beat‐wave experiments performed at Ecole Polytechnique in France. We first study the generation of long and homogeneous plasmas by multiphotoionization of low density gases and observe the density variation with time due to the ponderomotive force of the ionizing laser beam. In the Nd‐laser beat‐wave experiments we observe in the resonant conditions the generation of intense electron plasma waves. We also measure some daughter ion and electron waves generated by the decay of these primary electron waves by modulational instability (coupling with ion motions). These results show the importance of the ion hydrodynamic for the generation and the evolution of the accelerating electric fields in beat‐wave experiments.

  • the laser wakefield acceleration experiment at Ecole Polytechnique
    Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 1998
    Co-Authors: F Amiranoff, F. Dorchies, J.-r. Marquès, P. Miné, Brigitte Cros, Francois Jacquet, Victor Malka, G. Matthieussent, D Bernard, A Modena
    Abstract:

    Abstract A laser wakefield electron acceleration experiment has been set-up at Ecole Polytechnique. An electron beam with 3 MeV total energy is injected in a plasma wave generated by laser wakefield using the new LULI CPA laser (400 fs [FWHM], I 17  W/cm 2 ). The first results show an effective acceleration of the order of 1 MeV, with a maximum when the electron density is close to the optimum value for which the laser pulse length is about half the plasma wavelength.

  • A summary of the beatwave experiments at Ecole Polytechnique
    IEEE Transactions on Plasma Science, 1996
    Co-Authors: F Amiranoff, A Modena, J.-r. Marquès, Patrick Mora, P. Miné, Brigitte Cros, Francois Jacquet, G. Matthieussent, D Bernard, José Morillo
    Abstract:

    We present a summary of the beatwave particle acceleration program developed at Ecole Polytechnique. In dedicated experiments, plasma formation, plasma wave generation and saturation, and particle acceleration were successively studied and understood in detail. A maximum energy gain of 1.3 MeV was obtained, which is compatible with an accelerating gradient of 0.7 GV/m.
