NBI electrode for nuclear fusion reactor
Product details
A NBI (neutral beam injection) electrode made of oxygen-free copper for the JAEA Japan Atomic Energy Agency.
Production details
MTC built the electrode of the NBI device, which is a vitally important part of
the NBI. Electrical voltage of several KV will be applied to this product and
during usage high temperatures are being generated. To eliminate that heat, the
electrode is internally equipped with several water channels for cooling thus
having a high heat removal capacity. The largest NBI electrode MTC has built
until now is 515mm×230mm×6mm. We manufactured this product by using and
combining various bonding methods like vacuum brazing and torch brazing using
vacuum furnaces and hot press equipment, as well as composite joining techniques
such as EBW (electron beam welding).
