Abstract: The HT-7 is a super conduct Tokamak in China used to make research on the controlled nuclear fusion as a national project for fusion research. MDSplus has been used successfully in HT-7 fusion experiment in spring, 2004 for data storage and analysis for diagnostic subsystems.The reason to choose MDSplus as database for HT-7 data system and how to use it are introduced, the problem of which part of MDSplus library doesn’t work in multithread mode has been resolved. The experiment shows that the data system based on MDSplus works stably and can provide better performance for data storage and service.
