  AWAKE project, a proton driven plasma wakefield acceleration (PDPWA)
experiment is approved by CERN. The PDPWA scheme consists of a seeding laser, a
drive beam to establish the accelerating wakefields within the plasma cell; and
a witness beam to be accelerated. The drive beam protons will be provided by
the CERN's Super Proton Synchrotron (SPS). The plasma ionisation will be
performed by a seeding laser and the drive beam protons to produce the
accelerating wakefields. After establishing the wakefields, witness beam,
namely, electron beam from a dedicated source should be injected into the
plasma cell. The primary goal of this experiment is to demonstrate acceleration
of a 5-15$\,$MeV single bunch electron beam up to 1$\,$GeV in a 10$\,$m of
plasma. This paper explores the possibility of an RF photocathode as the
electron source for this PDPWA scheme based on the existing PHIN photo-injector
at CERN. The modifications to the existing design, preliminary beam dynamics
simulations in order to provide the required electron beam are presented in
this paper.
