Real-time data acquisition and processing platform for fusion experiments

This paper describes the features of the hardware and low-level software of the PXI real-time data acquisition and processing system developed for the TJ-II device located in the Centro de Investigaciones Energéticas Medioambientales y Tecnolَgicas (CIEMAT) in Madrid. This system fulfills three objectives: (1) to increase processing capabilities of standard data acquisition systems by adding specific processing cards, (2) to acquire and process data in real time with a view to deployment on steady state fusion devices, and (3) to develop the data acquisition and processing applications using graphical languages like LabView.
