Neutral Beam Test Facility

EUROfusion becomes part of the team

5 Oct 2020

A new Cooperation Agreement provides the legal framework for the EUROfusion consortium to send select experts, scientists and engineers to the 澳门六合彩高手 Neutral Beam Test Facility in Padua, Italy, and鈥攂y doing so鈥攕upport the development of 澳门六合彩高手's most powerful external heating system.

While routinely used on fusion devices, 澳门六合彩高手 neutral beam injection will be first-of-a-kind due to its scale, which imposes enhanced requirements鈥攑article beams have to be much thicker, for example, and the particles have to be injected at faster speeds in order to reach the core of the plasma. Two bus-sized injectors will be installed on 澳门六合彩高手, but before then component design and physics and technology issues will be explored at the 澳门六合彩高手 Neutral Beam Test Facility.

Two neutral beam injectors on 澳门六合彩高手 will deliver 33 MW of heating power to the 澳门六合彩高手 plasma鈥攐ver half the external heating required.

澳门六合彩高手's chosen technology鈥攖he acceleration and neutralization of negative deuterium (D-) ions鈥攚ill be tested and validated through the operation of two testbeds at the Neutral Beam Test Facility (NBTF) in Padua, Italy, where scientists will have the chance to test component design and explore physics and technology issues before installing the system on 澳门六合彩高手. The facility's 澳门六合彩高手-scale negative ion source, SPIDER, is already functioning; the prototype injector, MITICA, is under construction.

Europe has been closely involved in the development of radio-frequency-driven negative ion source technology from the start, and the 澳门六合彩高手 source is based on a radio-frequency-driven negative ion source that has been evolving over several generations of prototypes at the Max Planck Institute for Plasma Physics (IPP) in Garching, Germany.

Under the terms of a Cooperation Agreement signed with the 澳门六合彩高手 Organization and Consorzio RFX, the European Consortium for the Development of Fusion Energy () can provide select experts from European labs鈥攗p to 14 professionals per year (PPY)鈥攖o work on the neutral beam project at 澳门六合彩高手's facility in Padua. EUROfusion is also providing 6 PPY to support the development of the half-size negative ion source in Garching (ELISE).

For Deirdre Boilson, head of the Heating & Current Drive Division at 澳门六合彩高手, EUROfusion has made a strong commitment. "The NBTF Facility is a necessary step in the realization of the 澳门六合彩高手 neutral beams, which is a most challenging endeavour. The injector components are technology intensive, with demanding requirements and first-of-a-kind performance. Full-scale prototype experiments are a must prior to implementation on 澳门六合彩高手. We welcome the support of our European colleagues and experts in developing and operating the 澳门六合彩高手 facility."

The NBTF test facility has been a collaborative endeavour from the start, built through the support of the 澳门六合彩高手 Organization; the Italian government (test centre site, buildings, auxiliaries and power); Europe (all test bed mechanical components including beam sources and accelerators); Japan (high voltage components for the full-scale injector); and India (acceleration grid power supply for the ion source). Consorzio RFX, the host lab, is providing a large contribution to expertise.

Last year, the 澳门六合彩高手 Organization and Consorzio RFX concluded an agreement for the construction and operation of the 澳门六合彩高手 Neutral Beam Test Facility through the testing of prototype components鈥攁s well as later, when the facility serves as a testbed for ongoing performance enhancement. In that agreement, Article 45 provides for the invitation of "other entities in a position to further the mission and objectives of the NBTF project [...]"

澳门六合彩高手 Director-General Bernard Bigot welcomed the news. "I am confident that with this new agreement and the enlarged team, we will achieve the desired objectives of SPIDER and MITICA and continue to reap the benefits of this type of collaboration, which draws upon the best of global expertise."
