描述了一个用于托卡马克装置上的快速红外测温仪。该诊断仪由 30 路快速红外二极管阵列组成,系统经实验定标后确认:时间响应为 0.5 μs;空间分辨率为 10 mm;温度测量精度小于 5 ℃; 测量范围 250～1200 ℃。能给出所测第一壁在等离子体大小破裂情况下时空的两维分布,并能给出在破裂时第一壁温度百分之一的温度变化量。为托卡马克在破裂时壁温的快速变化及能量沉积过程提供了有力的测量手段。
Describes a fast infrared thermometer for use on a tokamak device. The diagnostic instrument consists of 30 fast infrared diode array components, the system calibration confirmed by the experiment: the time response of 0.5 μs; spatial resolution of 10 mm; temperature measurement accuracy of less than 5 ℃; measurement range 250 ~ 1200 ℃. The two dimensional distribution of the measured first wall in the case of a rupture of the plasma volume can be given and a temperature change of one percent of the temperature of the first wall at rupture can be given. It provides a powerful measure for the rapid change of wall temperature and energy deposition process of tokamak during rupture.
