EAST等离子体剖面数据可视化

EAST Plasma Profiles Data Visualization

EAST已经初步建立较为完善的分析数据数据库,相较于存储原始采集信号的一级数据库,科研人员称这个包含EAST各个子系统(诊断、加热、加料等)具体物理信息的数据库为EAST二级数据库.为了便于科研人员从EAST二级库中查看和分析等离子体剖面数据,采用Python及Py Qt开发了数据可视化图形用户软件.它可以分析比较来自不同诊断系统的剖面数据,具有将剖面数据用图形表示出来并改变图形属性等功能.同时在等离子体放电实验期间,提供了炮间分析等离子体剖面数据可视化的功能.本文介绍了EAST剖面数据可视化系统的设计方案与实现方法,同时也给出了系统的初步测试结果.

Experimental Advanced Superconducting Tokamak（EAST） has preliminarily set up more complete database of analyzing data. Compared with the primary database of storing the raw acquisition signals, the processed database includes processed data with physical meanings from EAST subsystems（diagnostics, auxiliary heating, fueling, etc.）. In order to make scientific researchers view and analyze the plasma profile data more conveniently, we use the Python and Py Qt to develop user graphics software. The software can analyze and compare plasma profile data from different diagnosis systems, use graphs to show data and change the graphic attributes, etc. The system also realizes the visualization of analysis plasma profiles between shots to aid plasma operation during the experiment. This paper introduces the design scheme and realization method of visualization system of plasma profile data, and also gives the initial test results of the system.
