Abstract

Experiments have recently been performed on the TCV tokamak to measure the plasma response to variations of the poloidal field control coil voltages. This technique uses multiple sinusoidal perturbation of these voltages, during normal plasma operation, with all of the feedback control loops functional. A new analysis technique allows us to extract from the data a direct measurement of the open loop plasma response, in spite of the feedback loop being operational. This original approach thereby provides a complete description of the reaction of any given plasma parameters to all of the 18 poloidal field coil voltage inputs.
