Abstract :
A far-infrared free electron laser driven by an L-band RF-linac has been developed in our institute. In the linac some kinds of noise exist and they induce beam instability. Optical cavity detuning characteristics and the effects of accelerator noise on the FEL are simulated by a 1-D pulse code. It is found that the time jitter and energy ripple of the electron beam during a macropulse modulate the laser power, and even decrease the power. Dependence of the noise effects on cavity detuning and beam parameters are also studied
