Stability and energy confinement of highly elongated plasmas in TCV
One of the principal aims of TCV is the creation and active stabilization of highly elongated plasmas. This implies high growth rates of axisymmetric modes and a very low stability margin. To stabilize such modes, TCV is equipped with a vertical position control system using a combination of slow coils outside the vacuum vessel (response time = 1 ms) and a fast coil inside the vessel (response time = 0.1 ms). The fast coil became operational in August 1996 and this paper describes the first experiments using both fast and slow coils for vertical stabilization.
