HL-2A多道中性粒子分析器的数据处理和试运行的初步结果

Data processing and preliminary results of compact neural particle analyzer system on HL-2A tokamak

根据多道中性粒子分析器的测量原理和HL-2A的特点,编写了基于Matlab的数据处理程序。该程序利用矩阵运算和下标定位技术,提高了代码执行的速度;使用了图形界面,使数据处理更加灵活直观。利用该程序对2009年的结果进行了处理,初步得到了离子温度的时间和空间分布。

Based on the diagnostic physics of compact neural particle analyzer （CP-NPA） and features of HL-2A tokamak, a Matlab code for data processing is written. The matrix operation and index-based array lookup technique is used to accelerate this code. And the graphical interface makes it visual and more flexible. Some of the data obtained in 2009 are analyzed using this code and the preliminary ion temperature profile of spatial and temporal distribution is obtained.
