Description
The BELLA petawatt (PW) laser facility at Lawrence Berkeley National Laboratory is pursuing development of 10-GeV-class laser plasma accelerators. In this presentation, we show recent progress toward this goal: guiding of 0.85 PW peak power laser pulses over 200 mm in plasma channels and electron acceleration up to 8 GeV. This was achieved by increasing the focusing strength of a capillary discharge waveguide using an independent laser for inverse bremsstrahlung heating of the plasma. Details of the laser guiding structure and properties of the input / output laser pulses as well as electron beams will be discussed.
