一台多功能发射度测量仪

A MULTI-FUNCTIONAL MEASURING INSTRUMENT OF EMITTANCE

测量束流发射度的方法很多,我们主要参照单缝移动、探针扫描、在函数仪上画相图和电偏转在示波器上连续显示相图的方法,设计了一台机械移动和电偏转相结合的发射度测量仪.

This paper describes the structure and results of primary experiments about a measuring instrument of emittance.The instrument consists of ma- chine moving as well as electric deflecting parts.It collects advantages from both machine moving and electric deflecting instruments. This instrument is simple in structure and multi-functional.It has fol- lowing functions:displaying emittance diagram by oscilloscope;automatically drawing ellipse circumference of the emittance diagram by function re- corder;measuring the phase space distribution of beam;displaying the normal- ized emittance and measuring the density distribution of beam.
