一种消色差等时性强流束三磁铁偏转系统
-
摘要: 描述了一种由三块二极磁铁组成,无四极透镜的消色差等时性磁偏转系统及其设计方法。根据该系统有关色差性和时差性的关系式与TRACE3D程序,设计了一个40MeV 、200A电子束的135°偏转系统,该系统显示了良好的消色差性和等时性。Abstract: A compact achromatic isochronousdeflecting system is described. It consistsof three dipoles and no quadrupoles areneeded between dipoles.On the basis ofachromatic and isochronous relatoins withoutspace charge for the system and TRACE3D program, a simple method is used to designthe deflm.An eecting system for intnse beaexample is worked out for 40MeV, 200Aelectron beam deflection.
