In early 1994 a new phase of JET operation started after the installation of a pumped divertor. Many new components have been mounted inside the torus: four divertor coils, divertor target plates, cryo pump, outboard and inboard poloidal limiters, new RT antennae (ICRH and LH), eight saddle coils for disruption control experiments, water cooling systems for divertor target, and various new or modified diagnostics. During disruptions and vertical displacement events (VDEs), these components and the vessel as a whole are subjected to dynamic forces due to eddy and halo currents. In the present paper some experimental results are described. At this stage no detailed evaluation is possible because the measurement system is limited and high resolution data recording was only available for a few signals.
