3-D effects on small signal gain for undulators with variable parameters 变参数波振器小信号增益的三维效应
These undulators all can increase the radiation power with their own parameters optimization, and the square tapered undulator gives the most outstanding effect. However, only the linear taper can improve the radiation spectrum distinctly. 结果表明,这四种波荡器都能在各自参数优化时提高辐射功率,尤其以正向平方锥化的效果最为显著,但是仅有正向线性锥化能够显著改善SASE辐射谱。
