Abstract :
Results are presented on the generation of quasi- monoenergetic electron beams with energy up to lGeV using a 40 TW laser and a 3.3 cm-long hydrogen-filled capillary discharge waveguide [1,2]. Electron beams were not observed without a plasma channel, indicating that self- focusing alone could not be relied upon for effective guiding of the laser pulse. Results are presented of the electron beam spectra, and the dependence of the reliability of producing electron beams as a function of laser and plasma parameters.
