Model Based Procedure for In Situ Error Compensation of Spatially Distributed Magnetic Sensors in RFX-mod2

This paper presents a model based procedure for in situ error compensation of magnetic measurements in fusion experiments. The proposed approach is validated on RFX-mod2, a toroidal device presently being upgraded with a sophisticated new magnetic diagnostic system and a state-of-the-art real time control system. The numerical simulations are performed with the code CAFE-VI; synthetic measurements are used to assess the reliability of the proposed method.
