摘要
IBM x射线源的正常工作条件是有一个倾斜的四极磁铁通电到20米的焦距。本文详细介绍了同步加速器光监测器所看到的磁铁强度变化的结果。特别是电子束的横截面出现垂直扩展和倾斜。此外，这些效应在两个偶极磁体中略有不同。这些效应可以通过推导在远离耦合共振线的情况下线性耦合的电子加速器运动的正常模式来理解。
Skew quadrupole effects in the IBM compact synchrotron
The normal operating condition for the IBM X-ray source is to have a skew quadrupole magnet energized to a focal length of 20 m. This paper details the effects seen by synchrotron light monitors as a consequence of varying the strength of this magnet. In particular, the cross section of the electron beam appears vertically expanded and tilted. Furthermore, these effects are slightly different in the two dipole magnets. These effects can be understood by deriving the normal modes for the linearly coupled betatron motions for the case of operation far from a coupling resonance line.<>
