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

1Abstract-- 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 apriori 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 2x0.4MW, 140GHz ECRH system equipped with a fast quasi-optical steerable launcher.
