Fusion Energy<\/strong> is one of the most promising energy sources for a sustainable future. With abundant fuel, virtually no CO\u2082 emissions, intrinsic safety, and unmatched energy density, fusion could provide clean and reliable power for generations to come.<\/p>\n <\/div>\n <\/div>\n

Within this ambitious global effort, the JT-60SA tokamak<\/strong>, a joint project between Europe and Japan, represents a crucial milestone. Among its many challenges lies the need for advanced components that enable plasma heating at extreme temperatures. Here, SAES RIAL Vacuum<\/strong><\/a>, in collaboration with Fusion for Energy (F4E)<\/strong><\/a>, has played a fundamental role.<\/p>\n <\/div>\n <\/div>\n <\/div>\n\n\n

Fusion energy: the context<\/h2>

Fusion reactions are fueled by isotopes of hydrogen, requiring only a few dozen kilograms of fuel to match the energy output of entire oil tankers. Unlike conventional energy sources, fusion is inherently safe and produces no greenhouse gases during operation.
In today\u2019s geopolitical landscape, the need for energy independence and sustainability has accelerated Europe\u2019s commitment to invest in skills, expertise, and industrial partnerships. Fusion, once a field dominated by publicly funded research, is now also attracting private investment thanks to its enormous strategic and economic potential.<\/p>\n <\/div>\n <\/div>\n

The JT-60SA challenge<\/h2>

Located in Naka, Japan, JT-60SA<\/strong> is the largest superconducting tokamak ever built. It has been designed to support ITER and to pave the way towards DEMO, the demonstration reactor that will prove the viability of fusion energy<\/strong> at industrial scale.
To achieve fusion, plasma must be heated to over 100 million \u00b0C<\/strong>. One of the most effective systems for this is Electron Cyclotron Resonance Heating (ECRH)<\/strong>, which uses high-power radiofrequency (RF) waves that resonate with the electrons in the plasma. Efficient transmission of this power from the source to the reactor vessel, however, requires highly specialized components.<\/p>\n <\/div>\n <\/div>\n <\/div>\n\n\n
