Abstract

We have developed signal processing routines for the Thomson Scattering measurement, which is planned for use in the next campaign of the JT-60SA large-scale tokamak experiment. This paper provides the data analysis system and its performance evaluated in terms of computation time and error. The sequential routine of determining the scattered light intensity from a simulated signal, including noise data from a 1 Gs/s high-speed sampling digitizer, and determining the electron temperature and density was tested for the first time on an actual machine. The data analysis system ensures that electron temperature and density can be calculated with reasonable relative errors and within a realistic time frame for operations on JT-60SA.
JT-60SA 汤姆逊散射数据分析系统的性能
我们为汤姆逊散射测量开发了信号处理例程,计划在 JT-60SA 大型托卡马克实验的下一次活动中使用。本文提供了数据分析系统及其在计算时间和误差方面的性能评估。从模拟信号(包括来自 1 Gs/s 高速采样数字转换器的噪声数据)中确定散射光强度以及确定电子温度和密度的连续例程,首次在实际机器上进行了测试。
