  The Low Emittance Gun (LEG) Project at the Paul Scherrer Institute (PSI) in Switzerland incorporates the development of an ultra low emittance electron-source to drive a cost-effective X-ray FEL*. For this purpose the source is based on field-emitter technology followed by high gradient (1 MV, 0.25 GV/m) acceleration. However, even with such a design the emerging electron beam is fragile and it is not evident that the low emittance can be preserved in the following acceleration process. Here we present a concept to achieve this goal, i.e., the status of the electron source development and an overview of the acceleration concept. Emphasis is given to a 250 MeV accelerator design, which is suited to serve as an injector for an X-ray FEL at 0.1 nm (12.4 keV) and boosts the electron beam into a regime where space-charge forces become less dominant.
