Design proposal of a connection system for ITER in-vessel magnetic sensors

This paper presents the results of a feasibility study aimed at the design of a mechanical support and electrical connector for in-vessel magnetic sensors compatible with remote handling maintenance. The work starts with the review of the reference design proposed in the ITER Design Description Documents and highlights the issues still open. A new design proposal is then developed taking into account the experience of similar applications developed for JET. The design proposal is supported by CAD modelling and thermal and electromagnetic analyses. In conclusion the developments necessary to qualify the proposal before considering it mature for production are outlined.
