对于盘状类型电极,确定其安全注入电荷水平的现行方法是按照一种平均电荷密度的方法给出的,虽然这种电荷密度在接近电极外周部处是较高的。本文描述了一种电极,该电极所产生的注入电荷密度在电极表面呈均匀分布,因此可以最大限度地使用电极表面。电荷密度为电流密度的时间积分,电流密度的改变可以通过增加电极曲率,以及在一个圆柱形绝缘管内开槽的方法获得。本文给出了一种新的数字方法,可用于确定其槽深和曲率。这种方法的优点是在维持盘状类型电极最大安全注入电荷水平的前提下缩小电极尺寸。本文同时也给出了一个最小的轮廓均匀电流密度电极以及其设计算法。最后我们给出 For disc-type electrodes, the current method of determining their safe injection charge levels is given in terms of an average charge density, although this charge density is higher near the electrode periphery. This article describes an electrode that produces an injected charge density that is evenly distributed across the surface of the electrode so that the electrode surface can be used to its fullest extent. Charge density is the time integral of the current density, which can be obtained by increasing the electrode curvature and by grooving in a cylindrical insulating tube. This article presents a new numerical method that can be used to determine its groove depth and curvature. The advantage of this method is that the electrode size is reduced while maintaining the maximum safe charge level of the disk-type electrode. This paper also gives a minimum contour uniform current density electrode and its design algorithm. Finally, we give
