In this lecture an overview of applications of incoherent Thomson scattering (TS) as well as collective Thomson scattering (CTS) will be given. These are the most accurate methods for measuring the electron and ion properties, because the method is direct and non-intrusive. A CTS system based on the fundamental wavelength of a seeded Nd:YAG laser, being developed for the high density, low-temperature plasma of the linear plasma generator Magnum-PSI will be described also. The small Debye length of dense low temperature plasma enables application of CTS at relatively short laser wavelength. The combination of this CTS system and existing incoherent TS system enables determination of electron density and temperature as well as ion temperature and plasma velocity of the near surface plasma. In this lecture, the theoretical background and experimental challenges of the work will be given along with some examples that demonstrate the capabilities of such systems.

用于测定低温等离子体中电子和离子特性的非相干和集体汤姆森散射

在本讲座中，将概述非相干汤姆森散射 (TS) 和集体汤姆森散射 (CTS) 的应用。这些是测量电子和离子特性的最准确方法，因为该方法是直接且非侵入性的。还将描述基于种子 Nd:YAG 激光器的基本波长的 CTS 系统，该系统正在为线性等离子体发生器 Magnum-PSI 的高密度、低温等离子体而开发。致密低温等离子体的小德拜长度使 CTS 能够在相对较短的激光波长下应用。该 CTS 系统与现有的非相干 TS 系统相结合，可以确定电子密度和温度以及近表面等离子体的离子温度和等离子体速度。在这次讲座中，
