摘要

为了产生100 keV以上、磁场强度在0.2 ~ 0.5 Tesla范围内的光子,先进光子源(APS)存储环中的波束可能需要波长/spl λ //sub 0/短于5 mm的波动器。我们研究了一种微波波束波导波动系统来产生这种光。波导结构由两个平行的反射面组成,这两个反射面可以从椭圆圆柱形波导中导出。该结构能够以极低的微波损耗支持偏转TE/sub /模式。考虑采用波束波导的微波环形谐振器电路来构造满足上述要求的波动器。研究了波束波导结构的微波特性,讨论了微波波动器的设计准则。

A microwave beam waveguide undulator for a brilliant above 100 keV photon source
For generation of photons above 100 keV with a magnetic field strength in the range 0.2-0.5 Tesla, an undulator wavelength /spl lambda//sub 0/ shorter than 5 mm may be needed with beam in the Advanced Photon Source (APS) storage ring. A microwave beam waveguide undulator system has been investigated for generation of such light. The waveguide structure consists of two parallel reflector surfaces that can be derived from an elliptically cylindrical waveguide. The structure can support deflecting TE/sub m0/ modes with very low microwave loss. A microwave ring resonator circuit employing the beam waveguide is considered to construct an undulator with the above requirement. Microwave properties of the beam waveguide structure have been investigated, and the design criteria for a microwave undulator are discussed.
