    电子云效应限制了几台加速器的高束流密度运行,例如SLAC和KEK的B工厂,CERN的SPS与PS.本文运用辛流形上的1-form李摄动法研究了2n多极场的电子云俘获效应,结果发现在多极磁铁(n＞1)的绝热区存在电子俘获.

    The electron cloud effect limits the performance of several accelerators with high beam current, such as SLAC and KEK Bfactories, the CERN SPS and the CERN PS. In this paper, the electron trapping in general 2n multipole magnet ( n is integer) isstudied, and we find that there exists electron trapping in the adiabatic region of the multiple magnet ( n＞1 ).
