NBI electrode for nuclear fusion reactor
A NBI (neutral beam injection) electrode made of oxygen-free copper for the JAEA Japan Atomic Energy Agency.
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 diffusion bonding with our core technology HIP, vacuum brazing and hot pressing.
