The general objective of the project is the definition, viability study, and development of the (novel) critical instrumentation of the IFMIF-DONES Li target by means of RF systems (DONES-LIDIA), including the implementation of demonstrators allowing the technique validation and its applicability to IFMIF- DONES. The novel RF instrumentation to be developed will have two main functions: the real-time monitoring of the Li thickness as an ultrafast Machine Protection System (MPS), and the beam footprint surface characterization for instabilities detection.
As DONES-LIDIA will be a cutting-edge instrumentation to be developed inside one of the most hazards nuclear environments, it is not possible to address the final design of equipment to be used in IFMIF-DONES in the framework of this project, mainly due to its limited duration and budget. However, this project is intended to validate the most appropriate RF technology for its applicability in fusion technologies, where the extreme operational environments are the main handicap, in particular, its application to the IFMIF-DONES Li target, where there is currently no instrumentation capable of operating with the installation requirements. Therefore, the development of RF technology for IFMIF-DONES can provide basic instrumentation for the operational control, inspectability, and monitoring of one of the most critical interfaces of the facility increasing the reliability and availability of IFMIF-DONES. In this way, the project will aim at defining the conceptual and even advanced design requirements for an ultra-fast MPS and real-time monitoring of the Li target surface of IFMIF-DONES, by means of scalable demonstrators to IFMIF-DONES requirements.
