Design and implementation of a common data analysis software for EAST tokamak

This paper introduces design and implementation of a data analysis and visualization software for EAST, which is super conduct Tokamak in China, used to make research on the controlled nuclear fusion as a national project for fusion research. The software provides uniform interface for different format data and adopts key technology such as ActiveX to get data from server. Matlab engine to calculate expression of signals and OpenGL to realize three-dimensional showing from array signals. User can easily finish data analysis and visualization only by using mouse and the showing can be scaled and rotated with interactive manner. (authors)
