摘要
研究了储存环圆真空盒中单根直导线结构清洗电极的一种电磁场形态，将此电磁场求解归纳为非轴对称双圆柱面边界的边值问题；推导了边界内电场势函数和力函数的解析表达式，以及非线性场表达式；指出该电场场强的四极、六极。
This paper presents an electromagnetic field pattern of single collinear wire cleaning electrode which is in the circular vacuum tube of the storage ring,which is reduced to achieving a solution of the boundary value problem of the electromagnetic field. The paper reports analytic expressions on the electric potential and field lines,and the non linear field expressions derived from the potential function. The paper indicates there is the sign variation of the quadrupole, the sextupole and the octupole of the electrical field on the radial direction.
