To test the efficiency of the blanket modules in a DEMO compliant environment, EUROfusion is considering the realization of a Volumetric Neutron Source facility (VNS). VNS will be a compact device, equipped with a DEMO-scale breeding blanket, pushing the active coils and the passive structures away from the plasma. From the electromagnetic viewpoint, this results in: the increase of the coils current needed for the definition of the plasma scenario; a reduction of the plasma shape controllability; the limitation of the stabilizing effect of the passive structures. To tackle these problems, the PMU is investigating two main design options: 1) Window-frame coil configuration 2) PF-in-TF configuration. In this paper, an electromagnetic analysis of the two design options in terms of plasma scenario feasibility and plasma controllability is proposed.

Abstract
To test the efficiency of the blanket modules in a DEMO compliant environment, EUROfusion is considering the realization of a Volumetric Neutron Source facility (VNS). VNS will be a compact device, equipped with a DEMO-scale breeding blanket, pushing the active coils and the passive structures away from the plasma. From the electromagnetic viewpoint, this results in: the increase of the coils current needed for the definition of the plasma scenario; a reduction of the plasma shape controllability; the limitation of the stabilizing effect of the passive structures. To tackle these problems, the PMU is investigating two main design options: 1) Window-frame coil configuration 2) PF-in-TF configuration. In this paper, an electromagnetic analysis of the two design options in terms of plasma scenario feasibility and plasma controllability is proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
