Abstract

The TCV vacuum vessel is continuously welded and has a low toroidal resistance for passive stabilization of the plasma vertical motion. Consequently large vessel currents, up to 200 kA, are induced by the loop voltage during breakdown. They create a vertical magnetic field of the order of 10 to 20 mT that must be carefully compensated to achieve discharge breakdown. This compensation as well as the creation of a poloidal field quadrupole rely on accurate magnetic measurements and a precise model of the electromagnetic properties of the vacuum vessel.
