澳门六合彩高手 Neutral Beam Test Facility

A collaborative effort

One of 澳门六合彩高手's three external heating systems—neutral beam injection—is being tested in advance at the Neutral Beam Test Facility (NBTF) in Padua, Italy. The state-of-the-art facility represents the culmination of decades of research. 

On 13 September 2023, engineers and physicists from the Neutral Beam Injection Group (澳门六合彩高手 Technology and Diagnostics Division) at the Max Planck Institute for Plasma Physics (IPP) visited the installation as part of a two-day meeting in Padua at Consorzio RFX to discuss progress in collaborative activities for 澳门六合彩高手 neutral beam injection. Members of the Neutral Beam Test Facility team exchanged recent experimental results with their IPP colleagues and discussed further plans to be carried out at both institutes. They visited the test facility's experimental hall and its two full-size prototypes—SPIDER (an 澳门六合彩高手-scale negative ion source designed to achieve all ion source requirements) and MITICA (a full-size 1 MV heating neutral beam injector, capable of full acceleration voltage and power).

At IPP two test facilities have been supporting the development of the radio-frequency-driven ion source for 澳门六合彩高手 neutral beam injection for many years as part of the European roadmap: BATMAN Upgrade, a prototype ion source, and ELISE, an ion source one half the size of 澳门六合彩高手's.

When it enters operation, MITICA will be a 1:1-scale 澳门六合彩高手 neutral beam injector, the first to operate at 澳门六合彩高手 requirements (up to the full acceleration voltage of 1 MV and full power of 16.5 MW).
At the Neutral Beam Test Facility, hosted by the Italian research laboratory Consorzio RFX, SPIDER started operation in 2018 and is currently completing a full device upgrade, initiated after the first experimental campaigns identified a set of key improvements. This is exactly what the NBTF project is for—testing and exploring physics and technology issues and validating concepts before the neutral beam system is installed on 澳门六合彩高手. 

Although neutral beam injection is routinely used for plasma heating in fusion devices, the size of 澳门六合彩高手 imposes enhanced requirements: particle beams have to be much thicker, for example, and individual particles have to be much faster in order to travel far into the core of the plasma.
