Abstract
A substantial modification of the toroidal complex of the RFX experiment, named RFX-mod2, is currently under completion, involving the whole core system of the machine and in particular the vacuum vessel, the entire plasma facing components and a wide set of in-vessel diagnostic systems [1, 2]. Novel technological solutions have been developed to satisfy challenging requirements in terms of electrical insulation and vacuum compatibility of in-vessel components and stringent geometrical constraints to comply with interfaces to existing machine components, in particular external coils and diagnostic systems. Such a development has been performed in collaboration with local industries in the framework of an industrial innovation project co-funded by Regione Veneto (POR-FESR 2014-2020, Regional Operational Program for the European Regional Development Fund). More recently the RFX experiment, being classified as a national high priority Research Infrastructure, has been awarded with additional funds in the framework of the Italian 'National Recovery and Resilience Plan' (Next Generation EU) for further improvements on plasma diagnostics and auxiliary plants, which are presently in progress. This contribution will present an overview of the technological solutions implemented and tested for the realization of the new components integrated in the RFX-mod2 machine complex. Moreover, a summary of the new systems under development and an update of the installation phase, planned to be completed by the end of 2024, will be reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
