Abstract: The designed maximum plasma discharge pulse length of EAST Tokamak is 1 000 s, to meet the requirement of long pulse discharge experiments on EAST Tokamak, this paper puts forward design and implementation of a long pulse real-time data system with the capacity of real-time data storage and distribution. It focuses on long-pulse data real-time storage system, achieves a segment storage design methods and gives the system test results. Experimental results show that the system is proved to be with steady and reliable performance and has an important application value in fusion fields.

Key words: real-time data, long pulse, segment storage
