A novel approach for generating and accelerating positron bunches in a plasma wake is proposed and modeled. The system consists of a plasma with an embedded thin foil into which two electron beams are shot. The first beam creates a region for accelerating and focusing positrons and the second beam provides positrons to be accelerated. Monte Carlo and 3D PIC simulations show a large number of positrons (10{sup 7}{approx}10{sup 8}) are trapped and accelerated to {approx}5 GeV over 1 m with relatively narrow energy spread and low emittance.
