Abstract
In ICF laser driver, the technique of precise target locating and guiding with multiple-beam is the core technique to couple beams and target on experiments. Its performance superiority will decide operation success or failure of the experiment on the whole facility. This paper will describe basic configuration of multiple-beam guiding and target locating system in detail, emphasize on the technique route, which makes the whole system to carry out the full closed loop control guiding beams and auto program process of shooting target, and makes the system shooting preparation time less than 30 minutes and shooting accuracy better than 30μm (RMS). The technique is successfully applied on ShenGuang-III prototype facility for two years.
