我们的激光离子源[1]的改进使我们能够大大提高其性能。整个系统的组成是：一个Nd: YAG激光器、源室和一个范德格拉夫激光器。主要变化有：1.1。一个更强大的激光。|改进的提取系统。通过这些修改，我们观察到电荷状态高达14+（通过飞行时间测量）。一安培范围内的离子电流可以直接在源外测量。施加脉冲提取电压将一个电荷状态的脉冲长度降低到~ 0.4 μs FWHM。
Improvements to our laser ion source [1] have enabled us to increase its performance considerably. The components of the whole system are: A Nd: YAG laser, the source chamber and a Van de Graaff. The major changes were:1.1.|A more powerful laser.2.2.|An improved extraction system.With these modifications we have observed charge states up to 14+(measured by time of flight). Ion currents in the range of one ampere could be measured directly outside the source. Applying a pulsed extraction voltage decreased the pulse length for one charge state down to ∼ 0.4 μs FWHM.
