abstract = {{The AWAKE experiment at CERN demonstrated in its Run 1 that it is possible to accelerate electrons in plasma wakefields driven by a self-modulated proton bunch. In Run2, AWAKE aims to increase the accelerating gradient in the plasma even further and demonstrate beam quality in order to be ready for high-energy physics experiments. In this framework, a new electron injector, consisting of an S-band RF-gun and a subsequent X-band bunching and accelerating section, capable of producing very short bunches with a small emittance, has been designed. In this paper, two different configurations of the X-band section and their corresponding high-power distribution systems are presented. The first one consists of three identical cavities to bunch and accelerate the beam while the second one uses a separate short structure for velocity bunching followed by three long, pure accelerating structures. A discussion of the strengths and weaknesses of each configuration is carried out and beam dynamics aspects are analyzed. Finally the X-Band power distribution systems are described with particular attention to the choice of the klystron, the pulse compression system and the waveguide distribution.}},
