摘要

在广义贝塞尔函数的帮助下，利用透明分析技术发展了双频阶梯锥形起伏器辐射理论。在该方法中，单个电子在轴上的辐射从单频和双频振荡器的阶梯部分推导为来自各个部分的场的总和。结果表明，阶跃段的辐射会相干叠加，并与阶跃段数量的平方成正比。这使得起伏器可以表现为一个高亮度同步辐射源。该分析提供了一个最简单的程序来估算锥形间隙起振器的场锥度。

Spectral Properties and High Brilliance Features of Two-Frequency Step Tapered Asymmetric Undulator Radiation

The theory of two frequency step tapered undulator radiation is developed with the help of generalized Bessel functions using an analytical transparent technique. In the approach, the radiation of a single electron on axis from the step sections of one-frequency and two-frequency undulator is derived as a sum of fields from the individual sections. It is shown that the radiation from the step sections superposes coherently and emits as proportional to the square of the number of step sections. This allows the undulator to behave as a high brilliance synchrotron radiation source. The analysis provides a simplest procedure to estimate the field taper in the tapered gap undulator.
