Abstract: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 PyQt 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.
