国际热核实验反应堆装置电子回旋辐射诊断强度绝对标定系统的热源设计与仿真

位于国际热核实验反应堆（ITER）9号窗口的诊断屏蔽模块由两个黑体源和两个远程可伸缩的透镜组成，该装置的作用是产生和引导黑体辐射，以校准ITER电子回旋发射诊断的径向和斜向视图。保持发射极的温度稳定对于精准源的正常工作至关重要，本研究针对这个问题，对ECE系统进行初步设计，优化调整发射极和恒温热源之间的距离，通过ANSYS仿真分析，获得辐射换热条件下ECE发射极不同路径的温度分布，以满足ITER中对于校准源的要求和约束。本研究对ECE系统结构设计及样机的研发具有一定的指导作用。

Heat source design of ECE diagnostic intensity absolute calibration system for ITER

The diagnostic shielding module located in Window 9 of the International Thermonuclear Experimental Reactor (ITER) consists of two black body sources and two remotely retractable lenses. The function of this device is to generate and guide blackbody radiation to calibrate the radial and oblique views of ITER electron cyclotron emission diagnosis. Keeping the temperature of the emitter stable is essential for the normal operation of the precision source. Aiming at this problem, this research conducts a preliminary design of the ECE system and optimizes and adjusts the distance between the emitter and the constant temperature heat source. Through ANSYS simulation analysis, the temperature distribution of the different paths of the ECE emitter under the radiant heat transfer condition is obtained to meet the requirements and constraints of the calibration source in ITER. This research has a certain guiding role for the structural design of ECE system and the development of prototypes.
