Active stabilization of n=0 and n=1 modes in the TCV tokamak
This paper discusses the possibilities for active stabilisation of n=0 and n=1 modes in the TCV tokamak. It is expected that, if the plasma is surrounded by a closely fitting shell, active stabilisation of n=1 modes will considerably increase the current limit of an elongated tokamak. If the n=0 growth rate is reduced, the beta limit may then be raised. The voltage, current and power requirements for stabilisation are discussed. It is shown that the internal coil is to be preferred for axisymmetric modes in TCV.
