Abstract：
In order to extract parallel beam from ion sources, it's necessary to design suitable electrode configurations in extraction zone. Taking the effect of the space-charge into account, the electrode configurations should vary with beam current density. A means of calculating extraction configuration of parallel beam with certain current density has been evolved from the space-charge limited current. By solving Poisson equation and Laplace equation, the potential distribution close to the strip beam has been gotten.
