本文从在美国德克萨斯联合实验托卡马克（J-TEXT）装置上研制红外多通道汤姆逊散射诊断系统的角度出发，设计了一套红外多通道汤姆逊散射诊断系统。系统的电源为3 J/50 Hz Nd：YAG激光器，激光器自上而下垂直注入等离子体。然后水平收集散射光，并将其传输到基于干涉滤光片雪崩光电二极管的多色仪进行光谱分析。该系统覆盖了半个等离子体横截面，提供了14个空间点，分辨率为2厘米。因此，该系统可以满足目前和不久的将来的J-TEXT的要求。本文详细介绍了系统的设计。
An infrared multi-channel Thomson scattering diagnostic system is designed from the viewpoint of development of the proposed system on the Joint Texas Experimental Tokamak (J-TEXT). A 3 J/50 Hz Nd:YAG laser, which is injected vertically into plasma in the direction from top to bottom, serves as the power source of the system. The scattering light is then collected horizontally and is transmitted to an interference-filter avalanche photodiode based polychromater for spectrum analysis. The system covers the half plasma cross section, providing 14 spatial points with 2 cm resolution. The proposed system can thus satisfy the requirements of the J-TEXT at present and in the near future. A detailed description of the system design is presented in this paper.
