A Real-Time system for data acquisition, elaboration and actuator's control for magnetohydrodynamics instabilities in the FTU tokamak

A Real-Time system for the for data acquisition and processing in order to control the magnetohydrodynamics instabilities in tokamak is presented. It is based on both a-priori information derived from statistical treatment of a database and live measurements from plasma elaborated by diagnostic codes executed at different sampling frequencies accordingly to estimated signals bandwidth (0.01ms to 1ms). The actuator is the 2×0.4MW, 140GHz ECRH system equipped with a fast quasi-optical steerable launcher.
