Currently proposed energy recovery linac and high average power free electron laser projects require electron beam sources that can generate up to ∼1nC bunch charges with less than 1 mm mrad normalized emittance at high repetition rates (greater than ∼1MHz). Proposed sources are based around either high voltage DC or microwave RF guns, each with its particular set of technological limits and system complications. We propose an approach for a gun fully based on mature RF and mechanical technology that greatly diminishes many of such complications. The concepts for such a source as well as the present RF and mechanical design are described. Simulations that demonstrate the beam quality preservation and transport capability of an injector scheme based on such a gun are also presented.
