GeV-scale electron acceleration in a gas-filled capillary discharge waveguide

Abstract:

We report experimental results on laser-driven electron acceleration with low divergence. The electron beam was generated by focussing 750mJ, 42 fs laser pulses into a gas-filled capillary discharge waveguide at electron densities in the range between 10^18 and 10^19 cm^-3. Quasi-monoenergetic electron bunches with energies as high as 500 MeV have been detected, with features reaching up to 1 GeV, albeit with large shot-to-shot fluctuations. A more stable regime with higher bunch charge (20-4...
