Dalian Coherent Light Source will use a 300 MeV LINAC to produce fully coherent photon pulses in the wavelength range between 150–50 nm by high gain harmonic generation free electron laser(FEL)scheme.To generate stable FEL pulses,a stringent tolerance budget is required for the LINAC output parameters,such as the mean beam energy stability,electron bunch arrival time jitter,peak current variation and the transverse beam position ofset.In order to provide guidance for the design of the Dalian Coherent Light Source,in this paper,the sensitivity of FEL pulse energy fluctuation to various error sources of the electron bunch was performed using intensive start-to-end FEL simulations.
