The ‘DIBA’ project has implemented this Tuesday a reliable and secure delivery scheme for critical data and control signals at the IFMIF-DONES, a future facility that will house a particle accelerator in Granada in which the materials to build in the future fusion power reactors. The Andalusian cluster “onTech Innovation” has coordinated this industrial research initiative, financed by the Ministry of Industry, Commerce and Tourism, and developed by the companies Orolia, JTSEC, Aaron and the University of Granada (UGR). ‘DIBA’ (Digitalization of Interlocks through Low Latency Communications) has as its main objective the design of sensors and digitalization of the signals produced for their subsequent deterministic, secure transmission with extremely low latency levels. To this end, the characteristics of the sensors linked to the generation of critical signals for IFMIF-DONES will be analyzed, the subsequent sending through reliable, cyber-secure and deterministic Ethernet networks. The environments in which the particle accelerator control systems are deployed must be able to allow the reliable propagation and delivery of the data from the different sensors and the control signals of the installation. According to its promoters, the nature of these control signals can be highly critical, since they are responsible for propagating fundamental messages for the protection of the installation and personnel, communicating the status of the fundamental accelerator systems, or propagating alarm signals. to plant operators. These signals also coexist with the accelerator’s multiple data sources, such as the signaling systems themselves, flows from various sensors or generic communications, which have usually been transported as analog signals, digital signals and over Ethernet networks, among others. Therefore, a complex communications environment is conceived, difficult to manage, and even susceptible to the effects of noise. DIBA proposes a solution that allows the digitized transport of all these flows, greatly simplifying the deployment, management, and maintenance of the accelerator network.
