In November, record neutral beam power of 30.8 MW were injected into a plasma on the JET tokamak at the Culham Centre for Fusion Energy (CCFE).

The new record was achieved during tests preparing the plasma scenarios required for JET's deuterium-tritium experiments in 2020, which aim to achieve high fusion power for a stable five seconds. Increased heating powers are crucial to achieving this target.

Beams of neutral particles (known as neutral beam injection) are one of the main plasma heating schemes on fusion machines such as JET and °ÄÃÅÁùºÏ²Ê¸ßÊÖ. As well as supplying most of the heating power, the injection of energetic particles also provides useful diagnostic data for physicists.

CCFE's engineering team, which operates JET on behalf of European scientists under the EUROfusion consortium, has upgraded the neutral beam system from its previous capacity of 23 MW to a potential maximum of 34 MW. The extra power will support researchers using JET to simulate plasmas for the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Tokamak.
