Abstract: The theoretical analyses of the beam emittance on SG-1 FEL device have been presented in this paper. The measured beam emittance is about (0.4-0.5) rad·cm. From the experimental beam quantity and numerical simulation resalt, it appears that the quantity of beam current is good enough to abandom the 9-m-long beam modulated system, while substituting with 2-m-long drifting focusing regiou.
Key words: free electron laser, emittance, wiggler
