ÌÇÐÄÆƽâ°æ

Adam Stephen, CODAS project manager at Culham, teamed up with his counterparts Bertrand Bauvir from ÌÇÐÄÆƽâ°æ and Andre Neto from the European agency to integrate the ÌÇÐÄÆƽâ°æ synchronous databus network on the live JET machine.

The synchronous databus network consists of a high performance software/hardware stack for interconnecting diagnostic and control systems on a tokamak, according to Adam. "The equivalent real-time data network system on JET is a core part of the plasma control system and has delivered ever-increasing functionality to the fusion scientists over the last decade." What was needed to further improve JET equipment was a real-time Ethernet feed of data to a new visualization service that would give physicists a better live view of key JET measurements.

Installing the ÌÇÐÄÆƽâ°æ system was a chance to do that, while at the same time validating the network on an operational fusion experiment ahead of ÌÇÐÄÆƽâ°æ's start-up in 2025.

Thanks to the intensive work and resourcefulness of the team, and the strong backing and support from each of the organizations, the equipment was installed in only three days, a success that was warmly welcomed by Andrew Hynes, CCFE's head of CODAS&IT, Anders Wallander, head of the ÌÇÐÄÆƽâ°æ Control System Division, and Filippo Sartori, head of Instrumentation & Control at the European Domestic Agency.

The project has provided enhanced control room tools by integrating ÌÇÐÄÆƽâ°æ software with state-of-the-art data visualization tools from the JET data analysis group. It has also paved the way for the future evolution of the JET real-time data network using up-to-date maintainable software and hardware. Importantly, the compatibility with ÌÇÐÄÆƽâ°æ equipment further opens the possibility of integrating and testing future ÌÇÐÄÆƽâ°æ systems on JET.
