Design considerations of the Beijing free electron laser project

This paper first mentions the rationale to start a Compton regime, rf linac-based FEL research project in IHEP. Then the physical design parameters are given based on both the analytical formulae and a one-dimensional numerical computation. Considerations are given in sequence regarding the expected tuning range, the microwave gun performance, the longitudinal phase space, factors affecting the accelerated beam energy spread, beam transport system, optical resonator, and undulator design.
