Status of the engineering design of the IFMIF-DONES Central Instrumentation and Control Systems

Abstract This work presents the current status of the design of Central Instrumentation and Control Systems for the IFMIF-DONES plant. IFMIF-DONES is the International Fusion Materials Irradiation Facility-DEMO Oriented NEutron Source, an accelerator-based neutron source producing a high-energy deuterons beam focused on a fast flowing liquid lithium jet to generate high-energy neutrons via stripping reactions. The intensity and irradiation volume is suitable to generate material irradiation data for design, licensing, construction and safe operation of the DEMO fusion reactor. After a general overview of the current status of the design of the overall architecture, a particular attention is given to the data management including the EPICS control framework, the general rules and criteria for the design and implementation of the HMI system, and the timing system solution composed of a three-layer distribution network to deliver time at each element of the plant that implements an optimal trade-off between timing performance and cost. Eventually, the next design steps and future work are outlined.
