A Continuous Data Acquisition System Based on CompactPCI for EAST Tokamak

For the purpose of long time data acquisition with high speed, a continuous data acquisition system based on the CompactPCI technologies was designed and developed for long time operation of the EAST tokamak. The system can continuously capture data for more than 1000s at 100 k sampling rate and provide the ability of real-time data view and access during the discharge. This paper describes the detailed information of the system including the system structure, workflow, data acquisition card, data transfer and data storage, as well as a discussion of the data access method. The system has been designed and developed and will be demonstrated in the next campaign of the EAST tokamak. The future work is also discussed.
