The extracted beam current depends on operating parameter of source, extraction voltage and cathode material.
引出束流大小与源的工作参数、引出结构和电压以及阴极材料有关。
The results show that the extraction time and collision loss are decreased by increasing extraction voltage, but the sputtering loss increases and collection ratio decreases.
模拟结果表明,增加引出电压可以缩短引出时间,降低碰撞损失,但是增加了溅射损失,使得收集率降低;
But the ion extraction time does not always decrease with the applied voltage.
但是,离子引出时间并非一直随电压的增加线性减小。
