RFX is a magnetic confinement toroidal machine based on the Reversed Field Pinch (RFP) concept [1]. It is in operation at the ''Istituto Gas Ionizzati'' in Padua since a few months. A study of the magnetic configurations with null-field points (X-points) has been performed in order to analyze the feasibility of operating RFX with a magnetic divertor. A reasonable solution has been found by means of an optimization procedure, which takes into account both physical and technical requirements, such as uniform vertical field for equilibrium, plasma cross section, thermal and electrodynamical loads on the coils.

Abstract
RFX is a magnetic confinement toroidal machine based on the Reversed Field Pinch (RFP) concept [1]. It is in operation at the ''Istituto Gas Ionizzati'' in Padua since a few months. A study of the magnetic configurations with null-field points (X-points) has been performed in order to analyze the feasibility of operating RFX with a magnetic divertor. A reasonable solution has been found by means of an optimization procedure, which takes into account both physical and technical requirements, such as uniform vertical field for equilibrium, plasma cross section, thermal and electrodynamical loads on the coils.
