Description: esults are presented on the generation ofquasi-monoenergeticelectron beams with energy up to 1GeV using a 40TWlaser and a 3.3 cm-long hydrogen-filled capillary discharge waveguide.Electron beams were not observed without a plasma channel, indicatingthat self-focusing alone could not be relied upon for effective guidingofthe laser pulse. Results are presented of the electronbeam spectra, andthe dependence of the reliability of producingelectron beams as afunction of laser and plasma parameters.
