Sourcing new fusion technologies everywhere in Europe to foster your innovation…
In magnetic confinement fusion machines, plasma-facing components are subjected to high heat fluxes that can cause damages. Based on many years of research works on magnetic confinement fusion at CEA, fusion experts developed a software suite for high-performance thermal imaging diagnostics. ThermaVIP platform can directly exploit all your sensor data to improve process control and understand accelerated ageing and damage of materials under high thermal stress. Any industry or laboratory whose processes or machines involve control of materials at high temperatures could be interested in this technology : metallurgy and steel, cement, glass and plastic industries, manufacture of electronic components, power lasers, particle accelerators and any high temperature industrial installations or test benches.
Description of the Technology
The ThermaVIP (“Viewing Imaging Platform”) is a software platform which provides the necessary tools for the delayed and real-time exploitation of sensor data, including imaging, to facilitate the understanding of the observed process. This may involve, for example, analyzing the physical phenomena that have occurred in a tokamak to understand their impacts on the machine. ThermaVIP is based on a modular and open source architecture that allows new sensors, algorithms or graphic components to be easily integrated. Its unique graphical interface, designed for end users, offers an ergonomic solution dedicated to the visualization/handling of heterogeneous signals. Thermadiag offers software solutions to facilitate the operation of your imaging sensors during operations. ThermaVIP integrates software modules dedicated to the acquisition of infrared or visible films from sensors, their storage and archiving in a database that can be consulted later.
The device is different from other tools developed in the framework of plasma medicine in giving rise to an indirect treatment, with no direct contact of the plasma with the substrate, and no electric current flowing to it. Such gentle treatment makes it suitable to the application to very delicate surfaces, such as the cornea (eye surface). The plasma source has been developed by a team of plasma physicists, with expertise on plasma production at atmospheric pressure and radiofrequency power. The core team has developed a network of collaborations concerning chemical, biological and medical effects. The tool is very easy to use, and can be made easier by appropriate engineering, so that a medical doctor could in principle have just a on/off switch to operate.
Thermavip is based on 4 layers :
The Qt library which is the only external dependency of Thermavip. You will need a version of Qt >= 5.4
A Software Development Kit (SDK) composed of 5 shared libraries: Logging, DataType, Plotting, Core and Gui. Those libraries only rely on QtCore, QtGui, QtWidgets, QtXml and QtNetwork.
The plugins, dynamic libraries containing user specific functionalities based on the SDK. These plugins generally provide tools to interact with additional data format (like new video files), display additional GUI features or define new signal processing routines. A plugin can depend on a subset of the SDK or the full SDK. It can also use additional external libraries.
The Thermavip executable itself, which is basically just a plugin container. Its main purpose it to load the plugins from within the VipPlugins directory. Thermavip defines 2 different executables: Thermavip.exe that displays a Graphical User Interface (GUI) and Thtools.exe (same as Thermavip.exe but without a GUI and GUI related libraries, for real-time systems mainly).
Innovation and advantages of the offer
Better control of the processes through a better understanding of what is happening at the heart of the process (as for example the overheating of a component)
Keep control of this analysis tools: master the analysis tools with your own sensor, algorithms or graphic components
Easy integration into an existing sensor environment/monitoring system
Non fusion applications
Any industry or laboratory whose processes or machines involve control of materials at high temperatures could be interested in this technology : metallurgy and steel, cement, glass and plastic industries, manufacture of electronic components, power lasers, particle accelerators and any high temperature industrial installations or test benches. This software is directed toward operational and maintenance supervisors and help them visualizing /synchronizing / analyzing telemetry data and IR videos acquired. It provides High level tools to dynamically map a 3D CAD model of your installation.
In magnetic confinement fusion machines, plasma-facing components are subjected to high heat fluxes that can cause damages. These damages are reinforced by leakage currents that impose point/localized concentrations of heat and radiation. Therefore, the CEA – IRFM has developed high-performance thermal imaging diagnostics for Tore Supra’s and West’s Tokamaks, dedicated to protecting these components and providing a physical understanding of thermal phenomena. ThermaVIP is used daily on 3 tokamaks (WEST/FR, JET/UK, W7-X/DE) for real-time IR acquisition and offline analysis of sensor data.
