| Abstract: | A bunch by bunch beam energy spread monitor (BESM) with eight stripline electrodes has been developed and newly installed in the transport line of BEPCII, which can measure the energy spread of a single-bunch electron beam nondestructively. The theory of the BESM is based on a multipole-moment analysis of an electromagnetic field generated by a charged beam. This paper is a further work on the multipole-moment analysis, in which the physical concepts and calculation model are definitely defined. In addition, the BESM's sensitivity is calculated according to the calibration results, and the causes of the calculation errors are also investigated. |
