Popis: Guiding of relativistically intense laser pulses with peak power of 0.85 PW over 15 diffraction lengths was demonstrated by increasing the focusing strength of a capillary discharge waveguide using laser inverse bremsstrahlung heating. This allowed for the production of electron beams with quasimonoenergetic peaks up to 7.8GeV, double the energy that was previously demonstrated. Charge was 5pC at 7.8GeV and up to 62pC in 6GeV peaks, and typical beam divergence was 0.2mrad.
