The Smart project (Small wait ratio tokamak), led byUniversity of Sevillerecently obtained a significant milestone with the first generation of experimental plasma. This device stands out for its ability to change the plasma configurationin particular creating plasmas with negative triangularity.
This particular shape of the plasma, characterized by a curvature facing the interior of the Tokamak room, optimizes operational efficiency reducing the dispersion of particles and energy. In this way, a more stable confinement is obtained, an essential factor for the future development of merger reactors.
Professor Manuel García Muñozthe main manager of the project, underlined the importance of this result, marking the beginning of the Smart operational phase. The final goal of the research is to create a Risted melting reactor reactorcombining the advantages of spherical tokamakfrom the negative triangularity and of high intensity magnetic fields.
What is negative triangularity and because it is essential for nuclear fusion
There negative triangularity It refers to the particular shape of the plasma inside the Tokamak. In conventional tokamak, the transversal section of the plasma takes on a form similar to the letter “D”with the flat part oriented towards the center of the confinement chamber. This configuration is known how positive triangularity.
In the case of negative triangularityInstead, the curvature is reversed: the plasma takes on a more rounded and oriented form oriented form, reducing the impact of instability on the walls of the Tokamak. This approach has shown to significantly improve operational stability and energy confinementtwo fundamental aspects for the progress of nuclear fusion.
The introduction of the negative triangularity In Tokamak it represents a paradigm change for the future of nuclear fusion. This innovative configuration improves the efficiency of the merger, allowing you to design smaller reactors and with greater energy capacity.
The Smart project is the first tokamak spherical Designed to study negative triangularity in depth, defining new standards in the research on merger. A fundamental role in the development of Smart was played by Collaboration between the University of Seville and Princeton Plasma Physics Laboratory (PPPL)who contributed with his advanced skills in magnetic diagnostics systems and in simulation software.
The two responsible for the project, Manuel García-Muñoz and Eleonora Viezzerhighlighted the importance of developing Tokamak also accessible to universitiesthus allowing to expand the contribution to the research on the merger. The combination between spheveric tokamak and negative triangolarities A revolutionary strategy is being revealed, capable of redefining the boundaries of nuclear fusion and closer to the dream of a clean and sustainable energy.
Towards more compact and efficient mergers reactors
The design of the Tokamak Smart incorpora advanced technological solutions to improve the confinement of plasma and operational stability. Its spherical form helps Reduce the unstable fluctuations of the plasma and guarantees one more uniform distribution of heatthus optimizing the reactor’s operational efficiency.
Thanks to the partnership with the Ppplcutting -edge diagnostic tools have been developed, including a Thomson Scottering systemwhich allows you to measure precisely Electrons temperature and energy in plasma. These progress are essential to guarantee the reliability and operational longevity of Smart.
The start of the plasma generation in the Tokamak Smart represents a Fundamental milestone for research on nuclear fusion. The adoption of the negative triangularity It offers scientists a new approach to design more compact and efficient reactorsaccelerating the path towards an energy production sustainable and on a large scale.
This discovery is arousing great enthusiasm among experts, outlining New perspectives for the future of energy. Thanks to the joint efforts of the scientific community, the dream of a system clean, safe and unlimited energy based on nuclear fusion It is increasingly approaching reality.
