Electromagnetic disruption analysis in IGNITOR

• Disruption analysis with two numerical codes (MAXFEA and CarMa0NL).
• Evaluation of electromagnetic loads on IGNITOR due to disruptions.
• Cross-validation and benchmark of the two codes.
• Highlight unique potentialities of CarMa0NL code in disruption analysis.
• Quantification of effects of three-dimensional geometry and of poloidal currents.

The present paper reports a detailed analysis of disruptions in the IGNITOR tokamak. Two different numerical models are used (one axisymmetric, the other three-dimensional), in order to validate the results and to highlight specific effects due to different assumptions. The results show a good agreement between the two codes, when similar assumptions are made, and highlight the potential significance of three-dimensional effects.
