A CompactPCI-based continuous and real-time data acquisition system for EAST tokamak

For the purpose of long time data acquisition with high speed, a continuous data acquisition system based on the CompactPCI technologies is designed and developed for long time operation of EAST. The system can continuously capture data more than 1000 s with 100 k sampling rate and provide the ability of real-time data view and access during discharge. This paper describes the detailed information of the system. The system has been designed and developed and will be demonstrated in the next campaign of EAST.
