In a significant advancement for fusion energy research, the pre-series gyrotron TH1509UA has successfully undergone testing at the FALCON test facility, showcasing its potential for high-power applications in both the Divertor Tokamak Test facility (DTT) and the ITER project. This gyrotron, designed to operate at 170 GHz, has achieved a remarkable output of 1.02 MW at its output window, translating to an impressive 980 kW after passing through the Matching Optics Unit (MOU). This level of performance not only meets but exceeds the specifications required for the DTT project, marking a pivotal step forward in the quest for sustainable fusion energy.
Falk Braunmueller, the lead author from the Swiss Plasma Center at the Ecole Polytechnique Fédérale de Lausanne, emphasized the gyrotron’s efficiency, stating, “We have demonstrated an efficiency of 40% during five consecutive 100-second pulses, which is crucial for the viability of fusion energy as a practical power source.” This efficiency is particularly noteworthy as it indicates the gyrotron’s ability to maintain stable performance over extended periods, a key requirement for any future energy generation technology.
One of the standout features of the TH1509UA gyrotron is its success in preventing parasitic mode excitation, a common challenge in high-power gyrotron designs. This advancement allows for a wider operational range around the design parameters, which could lead to even greater power outputs in the future. While the current tests focused on meeting DTT specifications, there is potential for exploring higher power performance in short pulses, which could pave the way for breakthroughs in continuous wave applications.
The implications of this research extend beyond the lab. As nations increasingly turn to fusion energy as a cleaner alternative to fossil fuels, the development of efficient and reliable gyrotrons could play a crucial role in commercializing fusion technology. The ability to generate high power with minimal variations opens up possibilities for integrating fusion systems into existing energy infrastructures, potentially transforming the energy sector.
The findings from this research were published in the ‘EPJ Web of Conferences,’ which highlights the collaborative efforts in the scientific community to advance fusion energy technologies.
