最近，在EAST托卡马克实验中升级了一套新的汤姆逊散射诊断系统，该系统使用了多脉冲激光和多点观察体。这项诊断使用了一种新的光学激光对准技术来准确确定激光位置，以及一种新的透镜收集系统，使其能够测量更广泛的等离子体对象。一个复合控制系统，我们可以在几秒钟内得到结果。此外，还采用了一种新的数据处理方法，以获得更准确的结果。
Recently a new Thomson scattering diagnostic system was upgraded in EAST tokamak experiment using a multipulse Nd:YAG (neodymium-yttrium aluminium garnet) laser and a multipoint observation volumes. This diagnostic uses a new optical laser alignment technique that was made to determine accurately the laser position, and a new lens collection system that enables the measurement of wider plasma's object. A composite control system made we can get the results in several seconds. Furthermore, a new data processing method was adopted for much exact results.
