摘要:

介绍了一种软X射线多道能谱测量的新方法,该方法用软件实现实时采集、数据处理并通过软X射线能谱计算及时显示电子温度。和传统的脉高分析器(PHA)相比,道数和时间分辨率可用软件设定。新方法采用一台配有高速A/D采集卡的个人计算机获取原始的模拟信号,开发了专用的处理软件用来处理电子温度。新方法已经应用于HL-2A装置实验,与其它方法测到的电子温度具有较好的一致性。

关键词: 软X射线能谱测量, 软件脉高识别器, 电子温度

Abstract:

A soft X-ray spectrum measurement system is newly developed for the real-time acquisition, data processing and display of electron temperature. In this system, a personal computer with high-speed A/D acquisition card is used to obtain the original analog data and processing software is specially developed to calculate the electron temperature. Compared with PHA (Pulse Height Analyzer), the new system provides a way to set channel number and time solution by software. This method has been applied in the HL-2A tokamak experiment, and the result shows a good agreement with the electron temperature tested by other measurements.

Key words: Soft X-ray spectrum measurement, Software pulse height analyzer, Electron temperature
