Application Boundary Element Method to Compute the Potential of the Eight-Needle Electrodes

Abstract:

According to the electric potential on the eight -needle electrodes in vacuum, the discrete equations based on the indeterminate linear charge density (LCD) are established by the boundary element integral equations. The non-uniform distributions of LCD on the needle electrodes are calculated through solving a set of linear equations. With the help of the LCD, the potential generated by the multi-needle electrodes at any point in vacuum have been obtained. In this paper we have realized the numerical calculation of the static field distributions for multi-needle electrode system by the boundary element approach.
