The possibility of high acceleration rates has already been demonstrated by plasma wakefield accelerators driven by electron beams. The next necessary step is obviously the demonstration of high acceleration efficiency and good quality of the beam. One possible way to achieve both the efficiency and quality is to prepare matched drive and accelerated beams by removing a central slice from a single high-quality electron bunch (parent beam). For parameters of the parent beam given, the question arises how to maximize the number and energy of accelerated particles and minimize their energy spread and emittance. This question is addressed by LCODE numerical simulations. As a reference point, the design beam parameters of VEPP-5 injection complex are taken. Optimum shape of the beams, required plasma length, achievable energy gain and energy spread are found as functions of the plasma density and parent beam characteristics. The required control accuracy of adjustable beam and plasma parameters is determined.
