Thales and Marvel Fusion will cooperate in upgrading the laser system of the Extreme Light Infrastructure for Nuclear Physics (ELI-NP) in Magurele, Romania. With the upgraded laser, Marvel Fusion aims to validate key aspects of its technology for fusion energy. This will make Marvel Fusion the first private company to establish a scientific collaboration at the worlds most powerful laser facility ELI-NP. For Thales, this will strengthen its leadership position in the design, development and manufacturing of solid-state lasers for science, industry, and space.

Magurele, Romania, December 06, 2022. Thales, global leader in advanced technologies, joins forces with the German fusion technology company Marvel Fusion and the ELI-NP (Extreme Light Infrastructure - Nuclear Physics) in Romania to upgrade the laser system and to perform research relevant to nuclear fusion as a future new energy source.

Over the course of 2023, the three partners plan to enhance parameters of the laser system, like the temporal laser pulse contrast, enabling unique research capabilities of laser-based fusion processes. After the successful adaptation, Marvel Fusion will be the first private company to establish a scientific collaboration with ELI-NP, due to the complementary applicability of the Romanian laser system and Marvel Fusions technology.

As part of an ongoing cooperation with ELI-NP, Thales will supply a new stretcher unit that is used to stretch laser pulses over time, which initially reduces their peak power. The stretched, less powerful pulses can then be amplified and thereafter compressed again. This process is part of the Chirped Pulse Amplification, for the development of which Dr. Donna Strickland and Dr. Gerard Mourou received the Nobel Prize in Physics in 2018. Mourou is part of Marvel Fusions Science and Technology Board.

Marvel Fusion in partnership with Thales and ELI-NP will start the experimental campaign at ELI-NP in 2023. The German company aims to validate key parameters of the laser-matter-interaction between high-intensity laser pulses with durations of tens of femtoseconds (one femtosecond is one-millionth of one-billionth of a second) and nanostructured fuel targets. In the experiments, the scientists will examine the essential physical processes of the interaction and their optimization. Subsequently, the results will be published in a peer-reviewed journal in an effort to advance the field of laser-matter interaction.

With its potential to sustainably replace fossil fuels as the worlds primary energy source, fusion energy is widely regarded as the most promising solution to climate change and the prevailing energy crisis. Building on the results at ELI-NP and the cooperation with Thales, Marvel Fusion aims to show the core building blocks of its novel technology within 3 years as a precursor to building the first commercial power plants in the 2030s. The new technologies will therefore be able to increase the Unions economic resilience and contribute to the decarbonization of the continent, according to the Green Deal Agenda.

Fusion based on latest-generation short-pulse lasers can enable the EU to guarantee an advanced energy system says Franck Leibreich, Laser Solution Managing Director at Thales. With the most powerful laser system ELI-NP in Romania and the leading manufacturer of industrial short-pulse lasers, Europe needs to capitalize on its outstanding knowledge and first-class infrastructure to globally lead in laser-based fusion.

Thales joined the ELI-NP program in 2013 to develop and build the laser system. In 2019, the construction was finished by Thales and for the first time, a ten Petawatt laser pulse was shot at the facility. With two laser beams each reaching ten Petawatt of peak power, ELI-NP is the worlds most powerful short-pulsed laser system. At the facility, scientists research in fields ranging from laser-based nuclear physics over ion therapy for the treatment of cancer to astrophysical processes.

The ten Petawatt laser system is an astonishing power level for laser systems. Experimenting at ELI-NP means that we now enter a phase in our technology validation in which we can draw direct physical conclusions about scalable designs of our target structures and the laser-target-interactions, says Dr. Georg Korn, Chief Technology Officer of Marvel Fusion and former scientific director at ELI.

ELI-NP with its unique capability worldwide to provide 10 PW laser beams is expected to bring significant advances in basic sciences and important breakthroughs in applications of major societal interests, says Dr. Calin Alexandru Ur, Director of ELI-NP. The mission of ELI-NP is to act as a catalyst for connecting the research community with both the academic sector and industry and to become a hotspot for science, innovation and development. Embarking with Thales and Marvel Fusion in a high societal impact scientific collaboration dedicated to innovative technologies in laser-based nuclear fusion is an important step for ELI-NP in achieving its mission. ELI-NPs actions to capitalize on research potential, technology transfer and know-how are in line with the recommendations contained in the National Strategy for Research, Innovation and Intelligent Specialization 2022-2027 adopted by the Romanian Government in July 2022, which emphasizes the importance of scientific partnerships with the private sector and the development of international cooperation.
