This article describes the present upgrade of the RGM system, the magnetic fault detection system designed for RFX (named RGM, from the Italian acronym rilevamento guasti sistemi magnetici), to be fully compliant with the new device RFX-mod2, considering both machine and operational modifications. RGM was originally designed for RFX, and it was based on the symmetries of: 1) the magnetic structures of RFX windings and 2) the topology of the electrical circuits. Then, in the early 2000s, a refurbishment of RGM took place in view of the machine upgrade to RFX-mod. Nowadays, the present upgrade to RFX-mod2 requires further modifications to the RGM system, making it compatible with new machine and operational specifications. RGM will be equipped with several additional magnetic sensors to overcome some constraints due to its original working principle and refurbished with redesigned electronic boards based on state-of-the-art technologies and components. The new system is designed to be fully compatible with the existing hardware, in order to keep advantage of the strengths of the original system.
