Application of LHD Post Data Analysis Systems to the KSTAR Project

Most of the experiments of the LHD (Large Helical Device) Project are repetitive short pulse experiments. That is, a 10 seconds-long plasma discharge experiment is executed every three minutes. Therefore, it is important to grasp the results of the experiment as soon as possible to direct the ongoing experiment. The post analysis tools used for the LHD project provide important information to the scientists during the experiment. The first tool is the AutoAna. The AutoAna runs the programs automatically to maintain the dependency among the analyzed data. Another tool is MyView2. MyView2 is a python-based data visualization tool, and it has been developed mainly for visitors so that they may use MyView2 to retrieve and analyze the necessary data for their study soon after they arrive at NIFS. The graph layout and the data source can be flexibly customized using a GUI operation. In the central control room for the LHD project, approximately 10 computers are located at the center and display the latest results of the ongoing experiment using MyView2. The authors believe these tools are useful for other experiments other than the LHD project, and prove the usefulness by porting them to the KSTAR project.
