Abstract :
The laser wakefield electron acceleration up to 300 MeV has been observed in an underdense plasma driven by a 2 TW, 90 fs laser pulse synchronized with 17 MeV RF linac electron injector at 10 Hz. The electron acceleration was enhanced at a density higher than the resonant density due to gas ionization and self-channeling effects. The wakefield excitation has been confirmed by measuring the electron density oscillation of the plasma wave with the frequency domain interferometer
