Development of a high charge 10 GeV laser electron accelerator
Original language description
Recent demonstrations of all-optical multi-GeV laser wakefield acceleration (LWFA) have been enabled by University of Maryland's development of low-density, meter scale plasma waveguides generated in greatly extended supersonic gas jets. We present a review of our recent LWFA efforts, including experiments and simulations to benchmark plasma waveguide generation, a new 3-stage model for relativistic pulse propagation in meter-scale waveguides, and recent LWFA experiments using waveguides up to 30 cm long. These experiments demonstrate sub-milliradian divergence electron bunches with integrated charge >1 nC above 1 GeV, and energy spectra including ≲ 10 pC features above 9 GeV with tails extending to slightly beyond 10 GeV, representing a laser to electron conversion efficiency of at least ∼30%.
