AB  - Laser-plasma accelerators (LPAs) driven by picosecond-scale, kilojoule-class 
      lasers can generate particle beams and x-ray sources that could be utilized in 
      experiments driven by multi-kilojoule, high-energy-density science (HEDS) drivers 
      such as the OMEGA laser at the Laboratory for Laser Energetics (LLE) or the 
      National Ignition Facility at Lawrence Livermore National Laboratory. This paper 
      reports on the development of the first LPA driven by a short-pulse, 
      kilojoule-class laser (OMEGA EP) connected to a multi-kilojoule HEDS driver 
      (OMEGA). In experiments, electron beams were produced with electron energies 
      greater than 200 MeV, divergences as low as 32 mrad, charge greater than 700 nC, 
      and conversion efficiencies from laser energy to electron energy up to 11%. The 
      electron beam charge scales with both the normalized vector potential and plasma 
      density. These electron beams show promise as a method to generate MeV-class 
      radiography sources and improved-flux broadband x-ray sources at HEDS drivers.
