摘要: 对曙光一号自由电子激光装置电子束发射度的测量值进行了深入的分析。严格地计算了不同发射度的束流在摇摆器内的传输,计算了发射度对激光功率的影响。由此得出,曙光一号自由电子激光器可以省去9米长的束流选择段。

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
