Validation of a plasma contour identification code

The paper presents the results of the validation of the plasma contour identification code PLACID. This code has been developed to reconstruct the poloidal magnetic field configuration produced during the plasma pulses of the RFX machine. PLACID input data are the signals of electromagnetic probes measured during the machine pulses. A set of validation tests has been performed in order to check the accuracy of the procedure implemented in PLACID and its sensitivity to noise in data. Input data for PLACID code have been generated by means of a virtual machine which simulates the actual machine. The virtual magnetic field configurations have been compared with the corresponding reconstructed configurations.
